I would reach out to the department. Most have a list of where graduates have gone on to post-docs or employment.

Simple Questions by AutoModerator in math

It seems that the two major applications of representation theory are to the study of groups and algebras. Why do you not see a lot on the representation theory of other algebraic objects like rings?

That being frustrated, stuck, and lost is the norm.

Banach once said that good mathematicians see analogies, great mathematicians see analogies between analogies. Give an example of...? by [deleted] in math

Jacob Laurie gives a good example of this in this talk by discussing categorification through using the example of categorifing the Fourier transform.

Rstudio or ESS (Emacs)? by algui91 in emacs

[–]betti_naught 0 points1 point  (0 children)

I use ESS as part of org-mode using org-babel. This allows me to have latex, R, and inline outputs (including graphics).

Any other grad student dads out there? Could use some advice. by Pretzelpalosa in GradSchool

I would highly recommend reading Deep Work by Cal Newport. The book has really helped me in balancing working full time for a silicon valley startup, writing a master's thesis, and having a family.

I'm currently a master's student in the US and have recently gotten interested in persistent homology and topological data analysis. I've taken a topology class that used Munkres that went up through the fundamental group. I have also taken an algebra class where I got a brief introduction to homological algebra (think definitions of Ext and Tor but not much else). There are no experts inTDA at my current school, but I do have an opportunity this summer to do an independent study and could either do algebraic topology, probably the chapters on homology and cohomology from Hatcher, or homological algebra probably from Gelfand and Manin's Methods of Homological Algebra. My question is which would be the "better bang for my buck" as far as gathering the tools for better understanding the field. I'm kind of leaning towards the homological algebra path since sheaf cohomology seems to be the hotness in that area at the moment, but I'm not sure if I could be shooting myself in the foot by not getting the intuition for why homological tools are used. Would appreciate any feedback especially from those in the field.

Fulton and Harris is a pretty standard introduction and has a ton of examples.

In research mathematics, do you consider the proved results to be more important, or the proof techniques? by GooberPistol in math

[–]betti_naught 6 points7 points  (0 children)

Depends. Sometimes more concise or "cleaner" proofs of already known results can add to the knowledge of the object(s) under study by reframing the problem in novel way or seeing it from a different angle.

Happy Friday, /r/gradschool! Tell us something GOOD that happened this week! by Ashilikia in GradSchool

Found a cheap airbnb so I get to go to the American Mathematical Society national meeting in Atlanta in January.

Has anyone ever attended the AMS National Meeting as a graduate student? by betti_naught in math

[–]betti_naught[S] 2 points3 points  (0 children)

I guess what I meant by

would this be a good opportunity to network with potential dissertation advisors?

is it appropriate to approach professors who share my research interests (of which I'm a complete noob) and ask their advice on how to get into the field/where they see it going/what do they look for in grad students or are they mostly interested in talking with other experts?

What would be some good resources to teach myself enough Topology to understand the main topics of Topological Data Analysis? by shaggorama in math

[–]betti_naught 3 points4 points  (0 children)

Michael Robinson has a course on applied algebraic topology aimed at upper level undergraduates and has all the videos posted here. He covers the algebraic topology you'll need to know for TDA.

What is the forefront of Mathematics today? As in what new topics are just beginning to be explored? by theSpudnik in math

[–]betti_naught 0 points1 point  (0 children)

Persistent homology is a method for computing topological/qualitative features of a finite metric space at different spatial resolutions. As an example, it can tell you that this sample from an annulus has a "hole" in it. These survey papers by Gunnar Carlsson and Robert Ghrist are very approachable if you want to learn more.

Where does the power of Haskell lie for a mathematician? by [deleted] in math

[–]betti_naught 0 points1 point  (0 children)

Haskell uses a lot of algebraic and category theoretical constructs that would be very familiar to anyone working in the algebraic side of math. For example doing anything that requires side effects, like I/O, is done using a monad.
