Hey /sci/
Which grad-level maths subjects would you recommend for a physicist who works largely with quantum and semiclassical systems?
I'm currently looking into integrable systems since I love Hamilton-Jacobi dynamics (I think they're related?) but I also love anything to do with logic or topology.
tl;dr: what are the god-tier grad-level maths subjects

Functional Analysis.
>>8689945
linear algebra
>>8689945
differential geometry
>>8689945
Computation and Complexity
Tie it in with quantum later
>>8689971
Very useful.

I think since you are not worried about pure math for your research the most important by far is LA. Then it's ODE/PDE, analysis and number theory. I would avoid "mathematical biology" though. It's mostly wasting your time solving the same old fishing problem when you should learn more generally about ODE and PDE.

Lie algebra

just do all of the pure math stuff lol
just learn everything
