Currently I am learning Quantum field theory, however I notice the lack of group theory knowledge especially Lie Algebra is quite fatal to my understanding. I hope to find some materials that can self study this field. My field of interest is mainly on quantum field theory and related theoretical particle physics.
My mathematical skill is on the level of standard beginning postgraduate students on physics, I learn mathematical methods from physics side instead of mathematics side, so I am not familiar with the style of Definition proves lemma corollary. I hope the material focus more on the application on physics theory.
Please recommend some lecture/course materials/books that may meet these requirement.
