From classical to quantum fields: an introduction to the path integral formalism

This book is an introduction to the modern ways of teaching classical and quantum field theories. A key tool is symmetries. For the resolution of classicaltheories, special attention is given to the definition of advanced or retarded potentials to ease the understanding of path integrals. The Path integral isused as the conceptual tool for defining the quantum field theories. The classical formalism is presented as a useful way to concretely compute observablesthat one defines in the path integral framework. The book contains special chapters which are devoted to new domains which have not been presented in othertexts. They include constructive quantum field theories and topological fieldtheory. The book is an advanced text which grew out from courses taught at the famous Ecole Polytechnique The book provides a modern approach to field theory, with exercises, questions and hints to assist in understanding the contentThe book is more technically advanced than competitors, especially in the uses of mathematics as a tool INDICE: Introduction - Relativistic Invariance - The Electromagnetic Field- Physical States - The Dirac Equation
