not really

golden bear
#

yes it is

flint forge
#

its almost too numbers based at time lol

willow pecan
#

There is a degree of randomness

tulip blade
#

It can be a little random but you dont randomly get in to a top school

golden bear
#

Explain how I got into a program with 2.95?

willow pecan
#

It is not entirely random

golden bear
#

with TA ship

tulip blade
#

Thats masters tho

sage python
#

A couple of us had gotten hyped about calculus and basically asked our teacher to do it asap since we thought it was cool (we were physics people at the time), she wanted to do the group theory but decided against it since she felt our class wasn't good enough with proofs for that

tulip blade
#

Im saying funded phd

sage python
#

So yeah idk we did the topics in a weird order

tulip blade
#

There is some randomness but they dont choose just anyone.

golden bear
#

But very small programs offer masters TA ship. Still hard and random

sage python
#

Nah

#

Randomness in grad admissions is as a result of, there are more qualified people than there are spots

tulip blade
#

My point was he wouldve likely been overlooked if they required the gre

karmic thorn
#

Seems fairly standard except for discrete math and groups. By discrete math, do you mean basic combinatorics?

sage python
#

Funded masters isn't common but also I don't think a lot of people are even looking at them

#

So it's a weird niche

golden bear
gray gazelle
#

How do you not forget the previous math you've learned?

tulip blade
#

Uh

sage python
#

That and also, the more common thing is to either go for PhD

tulip blade
#

I forget all the time

karmic thorn
#

By seeing it being used in different contexts, some ideas just stick as you do more math.

sage python
#

Or if you feel like you need more practice you do a masters, it's sometimes considered almost "remedial"

karmic thorn
#

But it's not bad to review/refresh anyway.

storm sleet
sage python
#

I don't want to use the term in the loaded way but

#

Let's say idk somebody goes to a school without as many resources or started in physics or something

golden bear
#

I consider masters like a "community college degree" that prepares you for PhD

storm sleet
#

That’s why my route is to get into an “early” masters in CS and moving into a PhD

sage python
#

Then yeah that's where you're looking most at masters. But I think if you're at that point you probably just accept that you'll likely pay

golden bear
#

NYU masters is consider a cash cow.

golden bear
#

After my masters, I am literally going to take a break. Probably 1-2 years.

storm sleet
#

Our college lets you get into grad school through some weird channels before you graduate

manic fox
#

consider tteppa during that break.

storm sleet
#

And our CS dept let’s you move from a masters to a PhD, without the GRE

tulip blade
#

Oh ok nice.

storm sleet
#

Ideally I’d do a masters in CS and a PhD in math

sage python
#

Good luck

golden bear
#

Good luck.

broken meadow
#

Luck.

sage python
#

Here we have a paid masters you can get to prep for PhD (a lot of people do it and get accepted back, also some schools have a program where their last year of undergrad at their home school is the first year of masters at UW Madison)

gray gazelle
#

I'm doing cs but imma be a developer for some company

sage python
#

Then there's a masters you can get on the way to a PhD

golden bear
#

i was planning to apply for a PhD program but all the deadlines were already passed.

gray gazelle
#

Tough

#

What u do then?

golden bear
#

I applied to two masters program. One of them was unfunded and the other was funded.

gray gazelle
#

Did u pick the funded one?

golden bear
#

Yea

gray gazelle
#

Does a masters specialize?

golden bear
#

They have a thesis and non-thesis option. Pure and applied courses are offered

gray gazelle
#

R u doing thesis?

golden bear
#

I'm unsure yet. I have a year decide

gray gazelle
#

R u doing pure or applied?

golden bear
#

Unsure about that too. As of now I am mixed with pure and applied

gray gazelle
#

Is there any specific field u like?

golden bear
#

I like Analysis

#

With ODE

sage python
#

Analysis is good stuff

gray gazelle
#

I thought analysis was undergrad

golden bear
#

Analysis a research interest

sage python
#

Analysis is an area of math

golden bear
#

^

sage python
#

You start learning it in undergrad but there's still current work being done

golden bear
#

There are five areas of math: Topology, Algebra, Stats, Geometry, and Analysis. Not sure If I am missing but these are the ones I know

sage python
#

Hard to really delineate like that

flint forge
#

youre missing a few hahah

gray gazelle
#

Algebra still requires research

flint forge
#

logic, combinatorics, etv

#

etc

willow pecan
#

Number theory is an area

flint forge
#

graph theory

#

TCS

sage python
#

I actually think stats is kind of its own subject since idk if there's an axiomatic characterization of the objects of study. And then like, a lot of stuff doesn't really fit under these boundaries cleanly

golden bear
#

From what I hear analysis is a somewhat like a dead area. Unless I am hearing wrong. I know complex analysis which is something I want to do is not an active area. However, Several variables complex analysis is starting to become popular

sage python
#

You're hearing very wrong

willow pecan
sage python
#

Analysis is arguably the most active field of math

willow pecan
#

No one likes SCV

sage python
#

And yeah SCV... idk maybe it's growing now but it's not nearly as prominent as most other things

golden bear
flint forge
#

also complex analysis isnt dead

sage python
#

Are you just an incorrect statements bot?

golden bear
#

Well whenever I say I want to do complex analysis research they say is dead.

sage python
#

I mean

#

Idk if much research is being done in single variable stuff

#

But SCV is def a thing

flint forge
#

also tons of complex analytic techniques are still popular

golden bear
#

Yea SCV is probably something I want to look at and see if its for me after I take complex this Fall

sage python
#

Complex geometry as well

sage python
#

But also there's a ton of analysis that's not complex analysis

#

Microlocal analysis PDE, harmonic analysis

tulip blade
#

Functional analysis is huge

#

Is that not analysis anymore lol

willow pecan
#

Dynamics

sage python
#

I mean

tulip blade
#

Operator theory

willow pecan
#

C* algebras

sage python
#

There's the usefulness of a subject

#

And then there's the research activity

willow pecan
#

Functional analysis is mostly complete

#

The outstanding questions are all bad

sage python
#

I feel like functional is very useful but idk if there's a lot of current research I'd classify as "straight functional analysis"

tulip blade
#

Wow awesome👍🏻

sage python
#

Like the theory of Banach/Hilbert spaces

flint forge
#

uh

#

what about that stuff jan does

willow pecan
#

Functional analysis was solved with a hundred adjectives describing different types of Banach spaces

flint forge
#

thats like 50/50 functional and model thh

#

thy

sage python
#

There are like, 5 people who work in that

#

I think this isn't an exaggeration

flint forge
#

hey thats all u need

sage python
#

Killer sometimes they group them up in a department but philosophically I don't think stats is a subset of math if only because your basic objects of study are not axiomatically defined

#

Like what's the definition of data?

flint forge
#

it already feels like only 5 people know my subject

#

so who cares

sage python
#

So stats at the core strikes me as being more empirical than math. That's my take at least. Obviously it's a very quantitative subject but it does differ from most math in that regard (I do consider probability to be part of math tho)

tulip blade
#

Probability is math

golden bear
#

Well Stats is applied math if you think about it

tulip blade
#

Its basically analysis

sage python
#

I thought about it

golden bear
#

if you combined stats and probabilty

broken meadow
#

i think stats has enough unique practices to distinguish it

sage python
#

It's quantitative and it does apply a lot of tools from math but again, I think it kinda is its own thing a bit

#

Like that's not trashing it at all

tulip blade
#

Stats isnt math

sage python
#

It's quantitative and has applications

golden bear
#

Stats is math but with data. So is really not math

sage python
#

But the basic objects are just different, and I think the methodology is a different style

tulip blade
#

fields can have overlap with math and not be math.

sage python
#

But yeah within analysis I'd wager PDE microlocal analysis is the biggest

#

Also harmonic analysis

tulip blade
#

Probability ?

willow pecan
#

PDE is the biggest in analysis

#

The outstanding questions in harmonic analysis are too difficult

sage python
#

Probability tru

#

Dynamics is active

tulip blade
#

PDEs is hugr

gray gazelle
#

I was wondering if there are any cute girls in any of ur classes who's a math major?

tulip blade
#

When i said functional analysis is big i just mean that i see a lot ppl with functional analysis/operator theory as interests idk anything about those fields tho

willow pecan
#

Dynamics isn't analysis

sage python
#

I think there are some people who are into it just not a lot

sage python
#

My department is very big on harmonic analysis

gray gazelle
#

Bro it would be nice finding a partner with similar interest

willow pecan
#

This is so cringe

gray gazelle
#

🤣

tulip blade
#

@gray gazelle Thats subjective but im sure youll find someoen in math if you want

gray gazelle
sage python
#

human if I'm gonna attempt to keep a straight face while answering you

golden bear
#

you said cute girls. Could have just said "Any girls"

willow pecan
sage python
#

The further you go in math the more male dominated things become

willow pecan
#

They're all lesbians

gray gazelle
#

Bro I would need to be attacted to the person

tulip blade
#

Cant comment on that

willow pecan
#

Because the straight women were all driven away by straight horny men

sage python
#

Now beauty is in the eye of the beholder and I don't know if I'm too fond of talking at large about the beauty of women in math

#

Like let's just not with that conversation topic lol

gray gazelle
flint forge
#

my girlfriend is hot and does math

#

so

gray gazelle
#

Ur right that beauty is in the eye of the beholder but im sure we all can agree Ariana grande is hot

sage python
#

I have met people I consider very attractive in math, same as outside of math lol. I'm not gonna attempt to speak for anyone beyond myself or do statistical stuff because that's weird

sage python
#

Like ah n% of the girls in math are good

#

So yeah that's what I'll say

cursive zinc
willow pecan
#

Ariana Grande is problematic

sage python
#

That's... creepy

#

Please don't say that even as a joke lol

#

It just pushes the atmosphere in a bad direction

gray gazelle
gray gazelle
flint forge
#

im not doxing my own girlfriend you creep

gray gazelle
flint forge
#

im only referring to onenine

golden bear
#

human are you sure a 12th grader (17 or 18)?

sage python
#

Max didn't even you see you say anything human you deleted first

gray gazelle
#

17

#

Wbu?

golden bear
#

25

gray gazelle
#

Dam u old

#

No offense

willow pecan
#

✨ gay dead ✨

golden bear
#

once you hit 18. time will fly

gray gazelle
#

I'm glad it will

sage python
#

Yeah college was the best time of my life

#

Grad school was tbh set up to be almost as good but

#

Covid 🙃

flint forge
#

i lost 25% of college

gray gazelle
#

What was best part about college for u?

flint forge
#

i guess you lost 20% of gradschool

#

college is just more fun in basically every way

#

than hs

sage python
#

More interesting classes, way better social life

gray gazelle
#

Being able to wake up later would be nice

golden bear
#

I would say sophomore year then first half of junior year. Second half of junior was starting to be the best

gray gazelle
#

For hs gotta wake up at 6

flint forge
#

more freedom, more parties, better classes, better friends, substances if thats ur thing

gray gazelle
#

Worst part

sage python
#

Meeting interesting people

#

It's just better™️

karmic thorn
#

I haven't seen uni yet, in person.

flint forge
#

lmao in my first year of college

#

i slept till noon

#

every day

gray gazelle
#

Oh yea uni has people from all over the state and even country so there must be plenty of interesting people

sage python
#

Damn you had no morning classes?

#

/you missed them?

karmic thorn
#

I'll finish my first year in August, would probably not get to see it till then.

flint forge
#

nope i just scheduled well

gray gazelle
sage python
#

Nice

flint forge
#

all my classes were 12:30 to 4

gray gazelle
#

I actually wanna wake up around 9-10 that sounds like the best time

flint forge
#

yeah its too late for me now

sage python
#

I'm doing this analysis summer school and my classes are at 9 which s u c k s but they record so I just tell myself I'll watch the recording later

flint forge
#

ironically inwake up at like 7 or 8

willow pecan
#

(Dami never does)

gray gazelle
#

I tried that for one of my online classes and Id rather go to the class

flint forge
#

i never watch recordings

#

i dont think anyone ever has

gray gazelle
#

Same It's awful

sage python
#

Yeah I need to like

#

Drink a bottle of soda and just watch them on 2x speed

flint forge
#

there arent a lot of people i can suggest coffee to and improve their health

willow pecan
hearty steppe
#

my nerves can't handle it

tulip blade
#

I drink multiple cups a day

#

how do you stay awake

willow pecan
#

By being a well adjusted person

broken meadow
#

i absorb my energy from the universe

#

Directly.

#

i do not need coffe

willow pecan
#

coffe

i drink yerba matte

#

its all u need

tulip blade
manic fox

erb

void sable
viral hill
#

it depends at what temperature you drink it lol, but, you normally want to cebar mate with water cooler than 75°C, because higher temps can ruin the yerba (kinda similar to tea leaves I guess), I have read that when most people consume mate it's around 37 -55 C, so it's safe, but nothing stops you from drinking an hotter infusion lol

#

good book for set theory from the basics?

storm harness
#

Do you already know first order logic?

velvet briar
#

Levin's discrete mathematics is free online, is a good read, and one of the easiest intros to logic and sets I've ever seen

gray gazelle
#

Good comic books or books like diary of a wimpy kid with slight pictures in every page now and then

#

What suggestions?

manic fox
#

hartshorne has a great series

#

Look up "Hartshorne GTM book" for more

#

Great book

hasty turret
#

Isn't that only one book?

#

How is that a series

manic fox
#

Yeah but it's very long

#

They originated as a series which he later compiled into his book

storm harness
#

So like, compiled from storytelling sessions at universities?

manic fox
#

yeah

#

i hear he was around universities a lot

storm harness
#

Man children's books' authors have got it easy

manic fox
karmic thorn
#

I suggest action thriller Analysis by Amann-Escher. 3 volumes so far.

hasty turret
#

I suggest baby rudin

#

It's written for babies

manic fox
#

he could have done so much more if he wasn't into the self destructive shit he was into

#

He spent his days doing something he called "algebraic geometry"

#

it's depressing really

storm harness
#

How to waste a life

manic fox
#

truly a tormented genius. He was a great comedian but a little insane

#

i feel for his family.

Hello, does anyone recommend a book that contains measure theory and functional analysis together for a beginner?

undone pine
#

Are there any books speaking about riemann convergence theorems (in particular about the monotone convergence theorem) on "basic" analysis level? I mean without measures, lebesgue and so on..

timber mesa
undone pine
#

@timber mesa By monotone convergence theorem I mean the following statement: if the sequence of functions f_n is increasing and riemann integrable and f_n-> f pointwise (f is Riemann integrable as well) then lim integral f_n = integral f

#

without the hypothesis that each f_n is continuois

#

so I can't apply Dini's theorem in this case

#

And i can't find the proof anywhere. In all articles that I found the proof involves measures

timber mesa
#

ah alright. I'm not sure if any book proves that without using the Lebesgue integral (which frankly, is probably the easier way)

undone pine
#

hm alright, thank you. I have this as exercice and I just wanted to check if my proof holds.

gray gazelle
#

riemann convergence theorems are a waste of time

#

i hate that stein shakarchi uses riemann integration for their fourier book

tulip blade
#

Isnt it the first course in the series?

gray gazelle
#

Any good books for geometry

timber mesa
gray gazelle
gray gazelle
sudden kindle
#

any book recs to learn about riemann surfaces ?

gray gazelle
#

guys, do you recommend any supplement for Abbott's R. Analysis?

storm sleet
obsidian valley
#

for model theory: Marker or Chang & Keisler or little Hodges

#

i have decided to buy a book so I can treat it as the light at the end of the tunnel that is aluffi

#

pls ping cause ever since they moved this channel I dont read it thx

obsidian valley
#

@sweet lotus when you have a moment

#

apparently I'm not the only one who pretends this channel doesn't exist anymore catThink

#

What are the possible goals

#

my goal atm is to learn model theory

#

I don't really have an end game for it

hearty steppe
#

its really like a broken down first semester analysis course book

#

does its job well, but if you are serious about math you gotta pick up a more dense analysis book

obsidian valley
#

little hodges or big hodges?

#

I have heard lots of good things about the little one on MO

#

👍

#

okay I will purchase it then

#

thank you petTheCat

gray gazelle
#

Don't say Rudin.

#

:D

#

Thanks Bruh.

hearty steppe
#

I was like that for a while but you'll understand why people say Rudin when you are ready to become a mathematician.

#

it is frustratingly hard to get through but I think I'm getting the gist of why people recommend it and why people strategize using supplementary material like Abbott to get thru it

#

having my second go with it now. The first time I tried reading it, I was too overwhelmed and obviously had to work a little on my proofs background. Spent my time doing that and easing myself into it.

I am starting to understanding that there is a certain tier of note taking and learning that goes into getting through Rudin. Each page and a half has you solving riddles that eventually has some pattern to build on.

#

and in a sense, it becomes engaging in a fun and eventually intuitive way, when you use supplementary material to your advantage every page you get stuck on

narrow talon
#

With all that

#

Do Rudin

hearty steppe
#

and mind you when I first openned Rudin, I didn't hate it, I just didn't understand how to get through it, and thats what frustrated me.

#

but I gave it another go last night, and I think im getting the hang of it and see why people recommend it so much

narrow talon
#

I’m working through it now, feel free to join

hearty steppe
#

how far are you in it Jason?

narrow talon
#

Err, at a fast pace mind you

#

Just first chapter, starting second tomorrow or overmarrow

#

Wait, Real and Complex right?

hearty steppe
#

oh no

#

lmao

#

not there yet

narrow talon
#

Oops 😬

hearty steppe
#

im still a pure newb

#

what do you call someone new to theoretical math? That's still where im at

narrow talon
#

I prefer Johnsonbaugh and Pfaffenberger. Not a popular book, but honestly better than Rudin as both a textbook and reference

hearty steppe
#

Pfaffenberger? What kind of name is that

marble solar
#

German

#

I used johnsonbaugh for discrete math and it was ok

#

Hopefully the real one is better

narrow talon
#

It is good! Basically the same level as Rudin, but with different organization and imo puts the emphasis in better places

#

It’s not excellent, but no real book is

marble solar
#

Stein and Shakarchi volume 3 is excellent

#

imo

hearty steppe
#

yea but S and S is after baby rudin tho?

narrow talon
#

Eh, that’s the one that can’t decide if it’s for grad students or undergrads right?

marble solar
#

Yeah ~ it's between the two

narrow talon
#

Err, I suppose that’s all of the S&S books

marble solar
#

The 4th volume is decidedly graduate

#

the 3rd volume depends where you're at

narrow talon
#

I’d honestly prefer just reading big Stein at that point

marble solar
#

At most schools it's graduate

#

at top schools it's undergrad

marble solar
#

but the notation and the exposition is clearer in Functional

narrow talon
#

We did big Rudin at that point during undergrad

marble solar
#

Where was that?

narrow talon
#

And Brezis, 3rd book is functional or measure theory? I can’t remember

#

NYU

marble solar
#

I didn't take grad real at UCLA, I did grad complex

#

I did grad real at CSULB, and we used S&S since CSULB is a weaker program

narrow talon
#

I only did grad functional

marble solar
#

I thought it was good

narrow talon
#

Was a joke after the undergrad analysis 2 course ngl

marble solar
narrow talon
marble solar
#

The "functional" book is more a hodge-podge of random stuff

narrow talon
#

Ah

#

I am a huge fan of Brezis

marble solar
#

Well all of my analysis profs at CSULB did their PhDs at UCLA

narrow talon
#

Fell in love with that book a long time ago

marble solar
#

Since it's so close - we largely used the same books, or same style

narrow talon
#

Gotcha

marble solar
#

It was an upgrade in teaching quality

#

a downgrade in how much we covered

narrow talon
#

I’m just familiar with some of the lecture notes from ucla and they’re pretty great

narrow talon
marble solar
#

e.g. my pure analysis prof didn't cover a whole lot

narrow talon
#

But motivation is important

marble solar
#

but my PDE prof covered more than what was possible at UCLA

#

Cuz of semester system

narrow talon
#

We covered nothing in functional, but I got a much deeper appreciation than I would’ve if a more “serious “ prof taught it

marble solar
#

The functional I took was an Applied Functional Analysis class

#

so we just did Green's functions, boundary value problems

narrow talon
#

A lot

marble solar
#

and compact operators

narrow talon
#

Sounds really fun though

marble solar
#

I ended up skipping first semester PDEs at LB, and just took second semester PDEs

narrow talon
#

At least as someone who really likes the applied part of functional

narrow talon
#

Common thing at NYU too

marble solar
#

That was a crazy class

narrow talon
#

First semester PDEs won’t mention sobolev spaces at all

#

Which is sad

marble solar
#

Yeah, day 1 was sobolev spaces

narrow talon
#

Makes sense

marble solar
#

We did a lot of regularity theory stuff

narrow talon
#

Encode your shit into the space and then use FA to solve your problems

marble solar
#

I had only seen basic wave equation or heat equation in like 1 or two dimensions

narrow talon
marble solar
#

it was my first time seeing n-dimensional PDE stuff, I was the best student in the class at it

#

Despite not doing first semester PDE

narrow talon
marble solar
#

Yeah, the only thing I used in my research was the heat equation

narrow talon
#

Err, equations? I really haven’t encountered nonlinear pdes tbh

marble solar
#

Heat equation is

#

u_xx - u_t = 0

#

Or something

narrow talon
#

My PhD program covers way less pde than I anticipated, only optimal transport as an elective

marble solar
#

Are you doing your doctorate at NYU?

narrow talon
#

Err, heat equation is nonlinear wtf?

marble solar
#

badly non-linear

narrow talon
#

I really know jack about pdes

narrow talon
marble solar
#

Ohhh fancy

narrow talon
#

Specialized program in probability and stats

willow pecan
narrow talon
#

Got in primarily because I’m interested in some bizarre applications

#

But of course you need PDE for probability

marble solar
#

Yeah, that's what my research was in

#

PDE & Probability stuff

narrow talon
#

So I'm spending my summer reviewing my basics and learning more about PDEs and SDEs

marble solar
#

I knew nothing about PDEs, and I still know nothing about probability

marble solar
#

The only probability class I took was Random Matrix Theory

narrow talon
#

I aced the final but bombed the rest of my stochastic analysis class

marble solar
#

From the same guy that taught sobolev spaces

#

Which had as a pre-requisite grad probability

#

but he just kinda let me in

narrow talon
#

But really need a lot more comfort with some of the naughty measureability bullshit

#

Which is really a bit sad for a prob PhD student. I really did not do well my first semester post covid and need to review a lot of the technical details of fundamental probability

#

Though it's not too hard

marble solar
#

Are you a first year?

narrow talon
#

I really wish there was a better book on path-space oriented stochastic analysis, but every one I've found is really quite awful

narrow talon
#

Oxford has three research groups I'm really interested in, FA, Stochastic, and DS

#

Stochastic is a given, but FA leans more towards nonlinear PDE

#

which I know very little about

marble solar
#

Try to keep an open mind! no need to shoe horn yourself into a topic just yet

narrow talon
#

Yeah, that’s just where I’m leaning towards

#

But at Oxford you only get one semester to choose an advisor

#

So I’m exploring (especially DL) now in more depth

#

Depth separation is a lot of FA, but really investigated largely by someone at NYU, not Oxford

marble solar
#

That is scary

small garden
#

and you don't get anymore chances?

#

like that's it?

narrow talon
#

So I’m leaning towards James Martin or one of the two DL people

narrow talon
#

But there’s lots of opportunities to interact with them

#

I may very well end up with someone in the math department and stats department

#

Just because my research interests don’t fall cleanly into a single person at Oxford

#

There’s also a lot of people who are firmly analytic focused probability, like Terry Lyons

small garden
#

and what is it that you want to study?

narrow talon
#

IPS based deep learning likely

#

So loss landscapes and such

pine flicker
#

no im jason

narrow talon
#

Pretty heavily dependent on analysis and statistical physics

#

As well as deep learning

do you think AI will 'destroy music'? (meaning AI is capable of making better music than us)

(Pretty heavily inspired by my mentors at NYU, Ben Arous did cowrite The paper relating the Hamiltonian of spin glasses to the geometry of loss functions of NNs)

But this is why I got into math actually, came from music to work in AI assisted music production

Hey guys! Do you think Apostol is a good choice for an EE indergrad?

Apostol's calculus V1 has mixed reviews, you can skim a bit to see if it works for you. V2 has better reviews, and his analysis book is encyclopedic.

But Paul's Online Math Notes should do the trick. You can also look at MIT OCW single variable calculus course.

The website has notes and PSets, as well as recorded video lectures.

I appreciate your recommendations, but I'm in search for textbook

karmic thorn

Then you could try Thomas' Calculus

Can you share your curriculum, in any case?

tiny elk

I heard Thomas' Calc is watered down

#

At least the new editions

#

Is that true

karmic thorn
#

Well, I can't tell without looking at what your curriculum covers

#

But for any non-proofs course in calculus

#

It should be good

tiny elk
#

I don't have my curriculum yet, I'm about to join college this year

karmic thorn
#

Ah

#

Okay

#

Then you could check out a few books and pick whichever you like?

tiny elk
#

I see

karmic thorn
#

Spivak is the standard rec for proper calculus

tiny elk
#

Of course

karmic thorn
#

Thomas' mostly for those not intending to major in math

tiny elk
#

A good prereq for Spivak that covers applications would be?

karmic thorn
#

You don't really need to know calculus going in

tiny elk
#

Oh

karmic thorn
#

But the book itself will take time to digest

tiny elk
#

I see

karmic thorn
#

That is a consequence of inherent difficulty, don't get bogged down

Hi... Is there a book that is sort of like "the algebra a numerical analyst needs" (but focused on stuff mostly other than linear algebra)?

willow pecan
#

Depending on what sort of numerical analysis you want to do, none to a lot

#

No satisfactory answer, I'm afraid

vagrant sedge
#

Seriously? I could be a lot? That is actually very much surprising to me.

willow pecan
#

For example, people working in numerical methods for odes/pdes use very little algebra

vagrant sedge
#

I was expecting "Nahh... it's mostly linear algebra"

willow pecan
#

Algorithm optimization in numerical linear algebra touches a bit on analysis on locally compact abelian groups

#

You have Fourier transforms which can be viewed algebraically

#

Nonlinear algebra/geometric programming relies very heavily on algebraic geometry

vagrant sedge
#

Cool. Any recommendations on the subject of geometric programming?

past storm
#

not too much outside of the standard curriculum

willow pecan
#

Ideals, Varities, and Algorithms by Cox, O'Shea, and Little is a classic

#

Sturmfels also has an Invitation to Nonlinear Algebra

You should learn more linear algebra

Try Friedburg

i'm reading combinatorics through discovery and I really like it

I don't think it contains anything that couldnt be done or appreciated by an 11th grader

its a pretty natural playground to practice more general techniques like proof by induction as well

#

.

#

that reminds me, I wanted to ask if anyone knows a good second intro combinatorics book, if that is a category that exists lol

#

i looked at combinatorics and graph theory by harris and a walk through combinatorics by bona

#

are those good?

warm glen

it goes more into the direction of enumerative and algebraic combinatorics

actually i do know bona, that is indeed a good and widely used book

What is a good introductory book for number theory? My goal is to develop math maturity

tulip blade

If youre an econ guy maybe analysis would be better

sage kelp
#

I actually started reading Abbott's analysis book, but it's crazy. Been enjoying it a lot actually, but maybe thought I could benefit more gaining some maturity first

timber mesa
sage kelp
#

So would it be better to start with number theory before approaching real analysis?

karmic thorn
#

Depends on your background, most places still use analysis and linear algebra as a first proof-based math course. I think it would be equally okay to start with introductory analysis.

sage python
#

I haven't looked at it more, I still think it's good?

karmic thorn
#

Yeah, Abbott seems great for an introduction.

tulip blade

#

Oh I was responding to Kaynex about Knapp

@velvet briar

The thing I like personally is that it does some noncommutative algebra

sage kelp
karmic thorn

See what works out better for you. Both are fine subjects for learning proofs in context.

#

(I would say analysis is inherently difficult as a subject too, but that's just how math is)

So even if you can't figure out ideas in the beginning, it's alright, you can ask for help here in accordance with #❓how-to-get-help .

oh my bad i misread not misspoke

what did you dislike about it?

the only problem I have with it is that I think it could restate core results once in a while. often after a question it will say "you've just proved the xyz-formula!", and you'll feel like "hmmm, have i? are you sure?"

which is slightly frustrating as it makes you second guess yourself a lot

What are some good introductory books on proof writing?

I'm trying to learn Trigonometry and Linear Algebra which would involve Calculus and got recommended that I start with proof writing...

I have no idea what proof writing is all about.

Unless its the same as what I was taught in Geometry class in High School (Hence Proved?), I assume that this would be more in general.

Background:-
The most bare basic High School math (no Calc), flunked Trig because I was unable to cram all the identities, also probably forgot most of the things so going through Khan Academy (currently Halfway through Algebra 1, hath been a smooth sailing ride)

A little bit of sequential logic, introductory set and graph theory (which isn't much I think).

I don't understand the introduction to proof books

Just like, start reading math and trying it

livid ermine

most intro to proof books cover logic, set theory, basic discrete maths as well as proof techniques. i think its very useful

marble solar
#

Yeah, but why not just start with linear algebra or real analysis

#

Just try to pick up as you go along

manic fox
#

proof books are literally a waste of time

sage kelp
#

I disagree. Those intro books just give you the tools to understand the structure of a proof. I think that once you have that, then you can adventure yourself in math and start learning by doing

glossy grove
manic fox
#

thonk proofs are intuitive tho

#

i never used a proof book and well

livid ermine
manic fox
#

im doing just fine KEK

manic fox
#

But real analysis and lin alg do have big theorems you need to do stuff in diff geo, so you can't really pick it up along the way. Tho really i guess you could, it just wouldn't be very efficient KEK

manic fox
livid ermine
#

really neither of you is gonna say how they're not the same?

tulip blade
#

you need to know analysis before you start doing analysis on manifolds

#

I dont think proof books are necessary but if you need it then do it. I did take one and thought it was a waste I wish it wasnt required at my school/

manic fox
#

You can very definitely nose around wrt proofs and follow what you think is right

#

My only intro to proofs was lke the first 5 pages of apostol's book KEK

#

the material needed to do proofs is not very lengthy, you need just to develop some good intuition and a nose for solving problems. You do this by actually solving problems in nature and not spamming artificial ENT problems in a proof book pepega

livid ermine
#

i guess its a difference in degree. but like i said, most proof books go over other things than just proof techniques, like logic, set theory, languages, graph theory, combinatorics etc. Stuff it will make it a lot easier to work with in other contexts, if you've seen them before.

#

I think the fact that the problems are artificial is good.

#

This might just be me, but personally, I often found it quite hard to know exactly which "resolution" to spell out a proof in. I think this is the case for a lot of newbie math people

tulip blade
#

I wouldnt really look at the graph theory and stuff in those books

manic fox
#

Like look

livid ermine
#

in a book like vellmans, there is no such ambiguity, because the objects you deal with are incredibly elementary

tulip blade
#

you should probably get the stuff that is necessary and move on

manic fox
#

you have to rip off the training wheels some point in time

#

There are only a few techniques you spam over and over

marble solar
#

Pick up the other stuff along the way

manic fox
#

And the issue is how to approach the problem in a clever enough way.

#

this is specific to the problem/field at hand usually

flint forge
#

theres a similar adage when learning to program that like

#

the best way to learn is to get excited about a project

#

and backfill

#

its not the worst strat in math esp. if ur self learning

#

but dragging yourself through an intro to proofs book is probably unnecessary unless you struggle in which case ofc you can just go back

manic fox
#

Like even though i can write a proof, im horrible at doing it when it comes to analysis, though im much better wrt algebra. A proof book won't teach me good analysis proof skills or whatever, analysis will. So the point is if you want to get good at or learn a subject, actually do that subject. The prereqs are very minimum wrt "proof knowledge" hmmCat

#

I am more than happy if I get to chapter 4 by December

note that spivaks calc spends more time on proofs and rigour than a typical calc textbook

its a lot of extra work

for a more... standard calc book, there are like 50 billion on the planet

honestly i dont think it makes much difference though

#

just do lots of exercises and youll be fine

#

no matter what text you pick

idk much about engineering math,but what purpose is a computational calc course supposed to serve?

#

A bunch of number bashing doesn't help anyone

quick hornet
#

lots of fields just need to number bash

#

any field that uses stats for example

What does computational calc refer to

quick hornet
#

which is most of science

willow pecan
#

Computing integrals?

#

Integration by parts?

hasty turret
#

Calc 1,calc 2 etc

willow pecan
#

Calculating derivatives?

hasty turret
#

The calc series

willow pecan
#

These are important in numerical methods

#

Which engineers definitely need to know

#

Finite element methods are fancy integration by parts

hasty turret
#

Can't they just learn those things while doing numerical methods

#

Why do they need a separate class

quick hornet
#

you have to learn them to read spivak anyway

#

spivak is literally just extra work on top of that

willow pecan
#

Because it is sufficient content for another class

#

There is already too much to cover in numerical analysis classes

quick hornet
#

also yea thats true too
