The in the preface to his quantum field theory book, Srednicki mentions that there is a set of lectures by Ed Witten on quantum field theory for mathematicians that is available online. Does anyone know where this is?
dx said:Hmm, maybe. But Srednicki said that it was available for free online.. but I can't find it.
The purpose of "Quantum Field Theory for Mathematicians" is to provide a comprehensive and mathematically rigorous introduction to the fundamental concepts and techniques of quantum field theory. It is intended to bridge the gap between the more abstract and physics-focused approaches to the subject and the more technical and mathematical treatments.
The book is primarily aimed at mathematicians who have a background in differential geometry, topology, and functional analysis, but are not familiar with quantum field theory. However, it can also be a useful resource for physicists who want to gain a deeper understanding of the mathematical foundations of the subject.
The book covers a range of topics, including classical field theory, path integrals, Feynman diagrams, renormalization, gauge theory, and supersymmetry. It also explores the connections between quantum field theory and other areas of mathematics, such as algebraic topology and representation theory.
One key difference is that "Quantum Field Theory for Mathematicians" places a strong emphasis on mathematical rigor and precision. It also incorporates recent developments in the field, including the use of supersymmetry and topological field theories.
The book can be used for either self-study or as a textbook in a classroom setting. It includes numerous exercises and problems, making it well-suited for self-paced learning. However, it can also be a valuable resource for instructors looking to teach a course on quantum field theory to mathematicians.
