Introduction to Quantum Field Theory
by Matthew Schwartz
Publisher: Harvard University 2008
Number of pages: 262
The approach I will take in this course is to emphasize that Quantum Field Theory is first and foremost a tool for performing practical calculations. In this regard, I will try to emphasize the physical problems which have driven the historical development of the field, and to show how they can be solved.

These notes offer a lightening introduction to topological quantum field theory in its functorial axiomatisation assuming no or little prior exposure. We highlight the algebraic formulation emerging from a formal generators-and-relations description.

We describe Feynman's path integral approach to quantum mechanics and quantum field theory from a functional integral point of view, where focus lies in Euclidean field theory. Gaussian measure and the construction of the Wiener measure are covered.

The book gives an exposition of the relations among the following three topics: monoidal tensor categories (such as a category of representations of a quantum group), 3-dimensional topological quantum field theory, and 2-dimensional modular functors.

Presently, all observational evidence points to the fact that Quantum Field Theory provides a good description of all known elementary particles. The scope of these lectures is to provide an introduction to the formalism of Quantum Field Theory.
