SUMMARY

To prepare for graduate-level physics courses such as General Relativity (GR), advanced Electromagnetism (E&M), Quantum Field Theory (QFT), and solid state physics, students should focus on essential mathematics. Key subjects include Analysis (using Rudin), Functional Analysis, Topology, Complex Variables, Abstract Algebra, and Advanced Calculus. While some students may consider self-study through resources like "Mathematical Methods for Quantum and Classical Physics" by Byron, a structured approach with formal coursework is recommended for a deeper understanding of the mathematical foundations necessary for physics.

PREREQUISITES
  • Multivariate Calculus
  • Differential Equations
  • Linear Algebra
  • Basic understanding of Partial Differential Equations (PDEs)
NEXT STEPS
  • Study Analysis using "Principles of Mathematical Analysis" by Walter Rudin
  • Explore Functional Analysis concepts and applications
  • Learn Topology fundamentals and their relevance to physics
  • Read "Mathematical Methods for Quantum and Classical Physics" by Byron for self-study
USEFUL FOR

Graduate physics students, aspiring physicists, and anyone seeking to strengthen their mathematical foundation for advanced studies in physics.

At my school, we apparently don't have a "math for physicists" type of course, which summarizes all the more advanced math that physicists need to know. The only requirement is: multivariate calc (finished), differential eqn (finished), linear algebra.

I heard, however, that the grad level physics courses here uses a lot of math. So, in order to prepare for those courses, which of the following math subjects should I strongly consider taking? (among those grad level courses, I'm considering GR, advanced E&M, QFT, and Atomic/optical physics, solid state physics).

1. Analysis (proof-based course, uses Rudin)
2. Functional analysis (requires analysis)
3. Topology (requires analysis)
4. Complex variables (fairly basic course) , different from complex analysis (which is more advanced)
5. Abstract Algebra (requires linear Algebra)
6. Advanced calculus (more like calculus techniques&PDE's for engineers type of class)

A. Would you be able to rank by the importance of the following subjects, as it is relevant to my physics studies?

B. Would you advise me to entrench myself deeply into the math, even though I'm not a math major? There's an alternative to taking 3-4 extra math classes, which is to pick up a book like Mathematical methods for Quantum and Classical Physics by Byron, and learn it over the summer. I started it , and I like the style. It is mathematically rigorous, but still very relevant to my physics studies.

Thank you.

what about partial differential equations
 
Well, what I reasoned was that I'll get enough PDE's in my intermediate and advanced E&M course that I don't really think I need an extra class for that.
