As seen in previous questions, I'm interested in gauge theory, although I have no idea how to do any of the mathematics, though i'd like to start. With that in mind, Are there any good sources that start at the basics?
As an aside, I've tried to decipher it through Wikipedia, although the rabbit holes required for all the terminology is long and dense, though this sentence is basically irrelevant.
Any “Mathematics for Physicists” at the suitable level will have an introduction to these things. In addition, most QFT books at the graduate level should have self contained introductions to these topics.
