What's a good book for Green's functions?

[DavitosanX]

Hello! I'm currently taking a course on partial differential equations, and we're using Asmar's textbook. We've reached Green's functions, and even though Asmar is a great book, I feel like I need a deeper study of the subject. Which book would you recommend to help me better grasp the theory behind Green's functions?

We had a prior thread on it that may answer your question:

The Green's function is called the impulse response function in engineering, a name which is more descriptive of the idea behind it. It is especially useful in linear systems.

Thanks for the link. G.F. Roach's book seems like the way to go. It's not expensive, which is always a good thing.
