Choosing math courses for theoretical/mathematical physics (grad school)

AI Thread Summary
In the discussion about useful mathematical courses for theoretical and mathematical physics, several key areas are highlighted. Topology and geometry courses, including topology, integral geometry, Lagrangian manifolds, Riemannian geometry, and differential forms on Riemannian manifolds, are deemed essential due to their frequent applications in mathematical physics. Algebra-related courses such as group theory, ring theory, Lie groups and algebras, and superalgebras are also noted for their relevance, particularly in areas like supersymmetry. However, model theory and number theory are considered less applicable, with limited use in the field. The importance of a comprehensive understanding of smooth manifolds is emphasized, along with the suggestion to include measure theory and mathematical analysis as foundational components for a robust mathematical physics education.

I'm not quite a mathematical physics guy, but I know just a thing or two about what some of it entails. Things like superalgebras and all of the topology and geometry stuff seem to come up in a lot of mathematical physics for sure.
 
Basically all of those topics crop up in mathematical physics somewhere, with the possible exception of model theory (I've never heard of it being used in physics but that doesn't mean that it hasn't). Number theory also has very few uses in mathematical physics, but they do exist (one example: using quantum statistical mechanics to study class field theory). Superalgebras generally crop up in supersymmetry, but I don't know if they have much use outside of that. I don't know anything about integral geometry so I can't comment on that. Everything else you mentioned, though, is widely used in mathematical physics.
 
I think everything you listed except for model theory is used on a regular basis. I also think you cannot limit yourself to Lagrangian manifolds. You need the entire theory of smooth manifolds.

I would also throw in some measure theory and mathematical analysis.
 
TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
