Hello over the summer I would like to study quantum field theory. I took two semesters of undergraduate quantum mechanics using Griffith's textbook. We covered the entire book in those two semesters. I also know my special relativity pretty well. Is that enough to self study quantum field theory rigorously. I also took a class in graduate classical mechanics and know Lagrangian, Hamiltonian formalism pretty well. Furthermore I have lots of experience with canonical perturbation theory.
