I study physics and currently taking a mathematical physics course. One of the topics is group theory and we will see the following topics: Symmetries, discrete groups, homomorphisms, isomorphisms, continuous groups, and linear transformations in phase space. This topic will be covered with the professor's notes, but I doubt that will be enough to study for the material. He recommends Herman Weyl's book "Group theory & Quantum Mechanics", but I've also skimmed through Herstein's abstract algebra and like it quite a lot. My question to you then is: Can I use Herstein's book to study for these materials? Namely I plan to read the chapter on Group Theory and that's it. What do you think? Should I opt instead for Weyl's book? It doesn't seem too mathematical by the way.
