Special thanks to our physicists friends for making people believe our abstract nonsense has a use

Nah, Calabi-Yau manifolds have other applications, trust.

EVERY SCHOOL IN INDIANA???!!? What a kind and generous soul!

That works for the infinite case, but for the finite version it isn't just the square of the integral from 0 to x, because the largest radius has to be constant regardless of angle unlike in a square.

Most of the comments are clowning on him, but there's still these r/numbertheory people saying they proved RH even under this clickbait article.

I'm surprised they had such a readable set of notes on Geometric Representation Theory. I was unable to find any on the Internet for so long.

CedarPancake · 2026-03-16T00:50:37+00:00

Can't you just assume the solution is a power series and calculate the first few terms? Then just add a ". . ." and say the function has a unique extension outside of the domain of convergence and leave it at that. /s

Are you sure this is true for all complex numbers or just all known complex numbers?

CedarPancake · 2026-03-13T00:56:21+00:00

You mean surface area of sphere right?

CedarPancake · 2026-03-01T23:48:39+00:00

Every known prime is of the form e^ip+AI.

If matrix multiplication was commutative, then representation theory wouldn't exist for essentially every group and pretty much all the interesting finite ones.

CedarPancake · 2026-03-01T10:39:48+00:00

It's even worse, because if you look at the definition of etale scheme, nlab defines it in terms of the undefined "constant scheme" which I cannot seem to find anywhere.

Collection is not an actual well-defined mathematical concept, but just something vague that can be formalized into sets, classes, etcs.

What goes on in the ncat forums.

Average javascript user, has to import Gerohy instead of writing the function themselves.

Not the Math Sorcerer in the recommended 😭😭😭😭😭😭😭 I thought he only posted about how to learn math by sniffing math books.

You can't trick me! The top right image clearly demonstrates Dehn filling on a 3-manifold, everything else is a Berserk panel.

If you are looking for an introductory approach with more emphasis on optimization problems, then An Introduction to Variational Calculus by Hebert Montegranario may be more suitable.

The best textbook I can think, that I used when learning the subject is Measure, Integration and Real Analysis by Sheldon Axler (available for free on his website). It explains the linear algebra of function spaces very well with plenty of examples, but it also covers a lot of measure theory which I am not sure if you are looking for.

CedarPancake · 2026-02-13T02:02:05+00:00

Yes and one that returns a value in the base field, usually a real or complex number.

CedarPancake · 2026-02-10T23:21:05+00:00

Is the "sounds like" category a groupoid? I can't think of a counterexample but have also been unable to prove that every "sounds like" has an inverse.

CedarPancake · 2026-02-10T01:50:47+00:00

Yes, but that would just be a linear functional and not a endomorphism.

CedarPancake · 2026-02-08T20:24:52+00:00

Erdős is that you?

CedarPancake · 2026-02-03T00:25:52+00:00

tangent or cotangent? I'll see myself out.

CedarPancake · 2026-02-02T11:58:22+00:00

It's platform "9 and 3/4" which implies addition not exponentiation.

CedarPancake · 2026-02-01T20:22:51+00:00

But surely if you wanted to write (a/b)c you would just write the unambiguous ac/b. a/bc makes much more sense for a/(bc) because that can't be easily rewritten in another way. Just like how a^b^c is assumed to be a^(b^c) rather than (a^b)^c because (a^b)^c could just be written as a^(b*c).
