Zusatztext This is a major contribution to the literature. Starting out with very elementary considerations, it proceeds to reach some of the frontiers in the field. From Classical to Quantum Fields is a fantastic resource to learn quantum field theory. It was a pleasure to read. Informationen zum Autor Laurent Baulieu is currently CNRS Research Director at the University of Paris, where he has long been the head of the Theoretical Physics Department. His main field of research is Quantum Field Theory, theTheory of Elementary Particles and Symmetries. He has been an organizer of many summer schools and workshops on various aspects of Quantum Field Theory, especially in les Houches and in the Cargèse Institute in Corsica.John Iliopoulos is Director of Research Emeritus at the Ecole Normale Supérieure in Paris, where for many years he was the head of the Theoretical Physics Department. His research was centred around theoretical particle physics. In 1970, in collaboration with Sheldon Glashow and Luciano Maiani, he predicted the existence of the charm quark and proposed the GIM mechanism, an important step in the construction of the Standard Model. He has also contributed to the development of supersymmetry (with Bruno Zumino and Pierre Fayet). He has received many awards, such as the Ricard Prize of the French Physical Society, the Sakurai Prize of the American Physical Society, the High Energy Physics Prize of the European Physical Society and the Dirac Medal.Roland Sénéor is Director of Research Emeritus at the French CNRS. He spent most of his career at the Ecole Polytechnique, where he established and directed the Graduate School and was the Head of the Department for International Scientific Relations. His research centered on the mathematical foundations of QFT: the axiomatic formulation, the constructive approach, the summability of the perturbation expansion and the study of dynamic stochastic models. He has received various awards, including the Langevin Prize of the French Physical Society. Klappentext Quantum Field Theory has become the universal language of most modern theoretical physics. This introductory textbook shows how this beautiful theory offers the correct mathematical framework to describe and understand the fundamental interactions of elementary particles.
