Geometry and Quantum Field Theory, designed for mathematicians, is a rigorous introduction to perturbative quantum field theory, using the language of functional integrals. It covers the basics of classical field theory, free quantum theories and Feynman diagrams. The goal is to discuss, using mathematical language, a number of basic notions and results of QFT that are necessary to understand talks and papers in QFT and String Theory.

The development of quantum field theory and string theory in the last two decades led to an unprecedented level of interaction between physics and mathematics, incorporating into physics such "pure" areas of mathematics as algebraic topology, algebraic geometry, and even number theory. This interaction has been highly fruitful in both directions, and led to a necessity for physicists to know basic mathematics and for mathematicians to know basic physics. Physicists have been quick to learn, and nowadays good physicists know relevant areas of mathematics as deeply as professional mathematicians. On the other hand, mathematicians have been more slow, intimidated by the absence of rigor in physical papers, and more importantly by a totally different manner of presentation. In particular, even the basic setting of quantum field theory, necessary for understanding its more advanced (and mathematically exciting) parts, is already largely unknown to mathematicians. Nevertheless, many of the basic ideas of quantum field theory can in fact be presented in a completely rigorous and mathematical way. Doing this will be the main goal of this course.
The textbook for the course is Quantum Fields and Strings: A Course for Mathematicians, AMS, 1998 (but I won’t closely follow it). Instead, I will rely heavily on the lecture notes.
Advanced calculus of several variables, basic differential geometry. Knowledge of physics is not required.
This is a course primarily for mathematicians. Physicists will not learn much in it, except how to present the ideas of QFT (which they already know) in a mathematical way. It is important to note that the instructor knows less QFT than a graduate student specializing in QFT or string theory.
