Based on a two-semester course held at the University of Heidelberg, Germany, this book provides an adequate resource for the lecturer and the student. The contents are primarily aimed at graduate students who wish to learn about the fundamental concepts behind constructing a relativistic quantum theory of Particles and fields. So it provides a comprehensive foundation for the extension to quantum chromodynamics and weak interactions, that are not included in this book.
Based on a two semester course held at the university of Heidelberg, Germany, this book provides a solid basis for postgraduate students wishing to obtain a more profound understanding of the foundations of quantum field theory. The book covers a wide spectrum of topic ranging from traditional operator and modern path integral methods, to different regularization and renormalization methods, asymptotic of Green functions, a particular view on the Renormalization Group, and spontaneous symmetry breaking in effective potentials. Much effort has been made to present the material in a transparent, detailed made to present the material in a transparent, detailed and structured way, which should help the reader to follow the material.
