**Summary::**What is (are) the best book(s) to understand the mathematics of Feynman diagram?

Hello,

Can anyone recommend some books for the mathematics of Feynman diagram? (I don't mind if they also include the physics; in fact it may be better).

Ideally I would need books that are very detailed (they don't skip steps in proofs to theorems, solutions to exercises etc.) but, at the same time, they take you from the basic level to a very advanced level.
