An Introduction to Quantum Field Theory
by Mrinal Dasgupta
Publisher: University of Manchester 2008
Number of pages: 48
Presently, all observational evidence points to the fact that Quantum Field Theory (QFT) provides a good description of all known elementary particles, as well as for particle physics beyond the Standard Model for energies ranging up to the Planck scale. The scope of these lectures is to provide an introduction to the formalism of Quantum Field Theory.

An introduction to Feynman integrals. In the first part of the course the author reviews the basics of the perturbative expansion in quantum field theories. In the second part of the course he will discuss more advanced topics.

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.

The approach is to emphasize that Quantum Field Theory is first and foremost a tool for performing practical calculations. I will emphasize the physical problems which have driven the development of the field, and to show how they can be solved.
