An Introduction to Relativistic Quantum Field Theory, authored by Dr. Silvan S. Schweber, offers a fairly simple explanation to familiar concepts in the subject for upper-level undergraduates, graduate and postgraduate students. Summary of the Book An Introduction to Relativistic Quantum Field Theory presents the contemporary developments in the field of quantum field theory. It begins with the analysis of the one-particle relativistic wave equations and continues to a second-quantized explanation of the system of n particles, signifying the association of this method with the quantization of old field theories. Following chapters discuss the Feynman-Dyson perturbation account of relativistic field theories, including the renormalization theory. The formulation of field theory in the Heisenberg picture is described extensively. Towards the end of the book, a brief description of the axiomatic formulation of field theory and an overview of dispersion theoretic methods are included. Appropriate number of problems is incorporated under various topics for better understanding and practice. About Silvan S. Schweber Dr. Silvan Schweber is the Professor of Physics, Emeritus and Richard Koret Professor in the History of Ideas at the Brandeis University. He obtained his Ph.D. from the Princeton University. Dr. Schweber was honoured with the 2011 Abraham Pais Prize for History of Physics. He has also authored books like Einstein and Oppenheimer: The Meaning of Genius; In the Shadow of the Bomb: Oppenheimer, Bethe, and the Moral Responsibility of the Scientist; Nuclear Forces: The Making of the Physicist Hans Bethe; QED and the Men Who Made it: Dyson, Feynman, Schwinger, and Tomonaga; and Mesons and Fields, V2: Mesons. Dr. Schweber is currently undertaking research in the history of sciences.
