Mathematical methods of many-body quantum field theory

"This book offers a comprehensive, mathematically rigorous treatment of many-body physics. Presenting many recent advances and clarifying difficult concepts, this book provides the background, results, and detail needed to further explore the issue of when the standard approximation schemes in this field actually work and when they break down. At the same time, its clear explanations and methodical, step-by-step calculations shed welcome light on the established physics literature."--BOOK JACKET.
