M. Fried presents a unified approach to the soluble and approximate models of relativistic quantum field theory, offering both theoretical insights and practical methods. The book is divided into two parts: the first focuses on the functional methods used in quantum field theory, while the second part addresses the models themselves, demonstrating how functional techniques can describe nearly all soluble and approximate models in the field.\u003c\/p\u003e\n\u003cp\u003ePart I covers essential topics such as the generating functional, the S-matrix, and the construction of generating functionals. It also includes noncanonical (chiral) generalizations and special discussions on quantum electrodynamics, providing a compact yet comprehensive overview of functional methods in field theory. In Part II, Fried explores perturbation expansions, soluble models, no-recoil methods, relativistic eikonal physics, and high-energy speculations.\u003c\/p\u003e\n\u003cp\u003eThis reprint edition includes a new Preface by the author, offering further insight into the development of the book and the evolution of quantum field theory. The level of presentation is accessible to students with a background in conventional field theoretic arguments, making it an excellent resource for anyone looking to transition to a functional approach to quantum field theory.\u003c\/p\u003e\n\u003cp\u003eAn invaluable text for students and researchers in theoretical physics, this book provides elegant functional techniques that are indispensable for anyone studying quantum field theory.\u003c\/p\u003e","brand":"Dover","offers":[{"title":"Default Title","offer_id":49938852118832,"sku":"Sarat_9780486828596","price":1779.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/9968\/4144\/files\/dover-book-default-title-functional-methods-and-models-in-quantum-field-theory-41284876632368.jpg?v=1775948169","url":"https:\/\/www.retailmaharaj.com\/bn\/products\/functional-methods-and-models-in-quantum-field-theory","provider":"Retail Maharaj","version":"1.0","type":"link"}
