Suppose we have [math]A,B [/math] which are [math] n \times n [/math] matrices. I want to compute the lie bracket [math] [X,Y] [/math] where [math] X(x) = Ax \ \& \ Y(x) = Bx[/math].

Can someone explain multiplicities in a decomposition of a representation into its irreps? In the context of finite groups, if it matters. For example suppose I have [math]\rho = \rho_1 \oplus \rho_2 \oplus \rho_3[/math], where each [math]\rho_i[/math] is irreducible and their corresponding representation spaces are [math]V_i[/math]. If [math]\dim V_1 = \dim V_2[/math], does that mean that [math]\rho_1 \simeq \rho_2[/math] (and hence [math]\rho = \rho_1^{\oplus 2} \oplus \rho_3[/math]) even if their actual actions on the vector space look different?

>> No.12752389

Kinda. The main idea is that for any set of vector spaces K = {v1, v2, v3, ... , v(n-1)} we can define another set S to be equal to the set of all linearly independent co products of the vector spaces who are elements of K. Obviously since K and S are not isomorphic and the kernel of their respective ring isomorphism are not rings we can apply Hodges lemma to easily show that within the category of Vector spaces any two elements A and B there exists a trisymetric mapping thus the dimension of B and the dimension of Φ(B) and A are not equal (where Φ represents Euler's Internalization Algorithm) this means that any scalar quantity alpha who is a member of B is also a member of its respective transition group representation, coincidentally the underlying set of B's transition group is B ⊕ A ⊕ Φ(A). The proof is as follows:

Let A be a subring of a field K and let x ∈ K and x!=0. Let φ:A->L be a homomorphism from A into an algebraicly closed field L. then φ has an extension to a homomorphism of A[x] or A[x^-1] into L. First ectend φ up to a homomorphism of the local ring A sub p where p is the kernel of φ thus without loss of generality we may assume that A is a local ring with maximal ideal m. suppose that mA[x^-1] = A[x^-1] then we can write
1 = a0 + a1x^-1 + ... anx^-n. with a being a member of m. multiplying each side by x^n we get (1-a0)x^n + bn-1x^n-1+...b0 = 0. with suitable elements bi in A. since a0 is in m it follows that 1-a0 is not in m hence 1-a0 is a unit in A because A is a assumed to be a local ring. dividing by 1-a0 we see that x is integral over A and hence that our homomorphism has an extension A[x]. If on the other hand we have mA[x^-1] !=A[x^-1] then mA[x^-1] is contained in some maximal ideal B of A[x^-1] and the intersection of B and A cointains M. Since m is maximal we must have that the intersection of B and A IS m. since φ and the canonical map A -> A/m have the same kernel

Is it possible to go to college after fucking up high school so hard? I love math but I've always been a terrible student; When I was a sophomore in high school I self-taught calculus and got a 5 on the BC exam (only person in my shit ass school who passed too lmao) but that year I got 3 Fs and a D- in Algebra 2 (my teacher rounded up a 53 because she knew I already knew the material). I never stopped self-studying I probably have approximately equivalent knowledge to the average 4th year undergrad. If I ever decide that I want to stop wageslaving and get serious about math is there any way I can do that? If I apply to a college I'm certain to be rejected because of my high school grades and even if I got into one how am I gonna stay motivated relearning all the shit that I self-taught, I wasn't able to motivate myself to do any of the assignments in algebra 2.

Hey frens, next semester I'm gonna do Differential Geometry (the classical one, we're using Do Carmo's book).

In the previous 1-3 threads one anon said that 4 last months of phd funding is too late to prepare a plan B outside of academia to another anon who was sick of the mainstream attitude of academics.

I'm just starting my phd and at first I like the idea of preparing for a good plan B, but it doesn't seem that much worth to invest like 1h/day average to learn coding or whatever while I have the opportunity to make my main plan work. I can't say I'm as enthusiastic for a plan B as I am for math, and all the time I can get either improving for it or rewinding is important. Plus I'm on pure mathematics, not even close to probability which could be useful for going into the private sector or something.
It seems to me that an all in is better, and if I decide to not get into academia I'll just pay the price and start a plan B from scratch.

one way is >>12767841 you can write any surface as connected sum of tori and projective planes. so you need to compute H(torus), H(projective space) and the effect of the connected sum on the homology (probably by Mayer-Vietoris), then you know everything.
other way is the cellular decomposition. there are very easy models for both orientable and non-orientable surfaces. these give you nice chain complexes from which you can compute the homology explicitly.

yeah a continuous map f induces a map [math]f_*[/math] on homology, so if f is a homeomorphism you get an isomorphism on homology groups because you have an inverse map [math](f^{-1})_*[/math]. basically this follows from the fact that homology is a functor

It seems to have this prestige within mathematics, and Grothendieck is considered such a legend, but whenever I start reading a textbook on the topic I just think "really, people are interested in this shit?"
Like an introduction might mention Bezout's Theorem about how many points at which two plane curves intersect and I just can't imagine giving a fuck. Like who cares? I really just don't care about gay little fucking curves in the plane.

This is something I think about often; people like Dyson got gud because they put in incredible amounts of work to get where they got: think 16 hour days of grinding through book after book.

It's a bit like endurance sports, in that there are freaks of nature who will sprint laps around you no matter what you're doing. In some cases, they've been training longer and harder or have cross-trained in sports you've never even heard of.

But can you beat your time from last year?

>>12769810
Once you get to the modern stuff, algebraic geometry is about studying schemes - locally, this reduces to commutative algebra so algebraic geometry gives you lots of geometric understanding of how commutative algebra works.

In this way, you can sort of think of it as just studying a more rigid version of something like complex manifolds - instead of asking that our space looks locally like C^n, we ask that it looks like the spectrum of some algebra over C. There's actually strong connections between these too - the category of compact Riemann surfaces is equivalent to the category of smooth projective curves over C, so you can study Riemann surfaces using the extra structure provided by algebraic geometry or vice versa (this principle is called GAGA - good example is Chow's theorem). It's pretty neat to look at differences/similarities between varieties and less rigid objects like manifolds and it can often help you understand one or the other better.

Hope this gives a better sense of why people might study AG. Personally, I just think the theory is really clean and elegant once you get deeper into it. It also has lots of connections to things like number theory (Weil conjectures, Shimura varieties, Honda-Tate theory), representation theory (representation theory of finite groups of lie type is hopeless without embedding in an algebraic group) and lots more.

Are there any courses on good universities open to the general public or students from other institutions?
Mine allows me to get credits through online courses from other institutions, so I need to know what opportunities are out there.
I'm particularly interested on courses about Algebraic Geometry, Algebraic Curves, Arithmetic Geometry and Commutative Algebra. Nothing too advanced though, I'm still starting on those areas.
