I see. Then, since the prerequisite seems to be totally up to what I will specialize on, I will skim through some of the above literature for now, and then I will peruse the one which I will need for any paper or on my research. I appreciate your advice a lot!
Thanks for your reply. I'd like to study math as a mathematician and physics as a physicist. I believe I can do both, since the areas of math and physics which I'm interested are closely related to each other. I have all the prerequisite knowledge both in math and physics, so I want to study...
I wasn't sure whether I should post this question in this category or "High Energy, Nuclear, Particle Physics", but I decided to post here, since I want to get opinions from the people who are studying the topics discussed in this category, not the experts on standard model or particle physics...
