The main part of this book is devoted to the simplest kind of Green’s functions, namely the solutions of that differential epuations with a delta function source. It is shown that these familiar Green’s functions are a powerful tool for obtaining relatively simple and general solutions of basic quantum problems such as scattering and bound-level information. The bound-level treatment gives a clear physical understanding of “difficult”questions such as superconductivity, the Kondo effect, and, to a lesser degree, disorder-induced localization. The more advanced subject of many-body Green’s functions is presented in the last part of the book.
