Path Integrals in Physics: Volume I Stochastic Processes and Quantum Mechanics

Comprehensive, detailed, and systematic, this volume presents the fundamentals of path integrals, both the Wiener and Feynman type, and their many applications in physics. Accessible to a broad community of theoretical physicists, the book deals with systems possessing a infinite number of degrees in freedom. It discusses the general physical background and concepts of the path integral approach used, followed by a detailed presentation of the most typical and important applications as well as problems with either their solutions or hints how to solve them. The book describes in detail various applications, including systems with Grassmann variables.
