Hello everyone! I want to study QFT and I want to know all of the required mathematics for it. I know most of quantum mechanics topics -wave function -schrodinger equation -state, operator -perturbation theory I know some of special relativity. And I almost familiar with einstein's notation. I don't know much about symmetries, group theory, and other abstract algebras. Please list me some of the required maths for QFT. Thanks in advance.
