AI Thread Summary
To study Noncommutative Geometry (NCG), a solid foundation in several advanced mathematical subjects is essential. Key prerequisites include Real Analysis, specifically at the level of Rudin's "Principles of Mathematical Analysis," and Complex Analysis, ideally using Marsden's "Basic Complex Analysis." A strong understanding of Topology, as presented in Munkres' work, is also necessary. Additionally, knowledge of Algebra, particularly Fraleigh's "An Introduction to Abstract Algebra," is crucial. Familiarity with algebraic geometry, homology, cohomology, and k-theory, as discussed in Connes' texts, further enhances preparedness for NCG.For those interested in studying Lie groups, it is important to have a grasp of both algebra and differential geometry, as Lie groups combine elements of group theory with differentiable manifolds.

What are the prerequisites to study NCG?

I know Real Analysis at the level of Rudin's "Principles of Mathematical Analysis", Complex Analysis at the level of Marsden's "Basic Complex Analysis," Topology at the level of Munkres, Algebra at the level of Fraleigh's "An Introduction to Abstract Algebra".

Probably algebraic geometry, homology and cohomology as pre-pre-requisites.

You can also see some remarks about k-theory in Connes text. So I guess that's another prerequisite.

OK. Guess I should wait a bit.

Lie group = group + differentiable manifold, hence knowledge in both algebra and differential geometry is needed.
 
I’ve been looking through the curricula of several European theoretical/mathematical physics MSc programs (ETH, Oxford, Cambridge, LMU, ENS Paris, etc), and I’m struck by how little emphasis they place on advanced fundamental courses. Nearly everything seems to be research-adjacent: string theory, quantum field theory, quantum optics, cosmology, soft matter physics, black hole radiation, etc. What I don’t see are the kinds of “second-pass fundamentals” I was hoping for, things like...
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...
