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 were taken during Sidney Coleman's lectures on Quantum Field Theory (Physics 253), given at Harvard University in Fall semester of the 1986-1987 academic year. These notes remain the principal source for the Physics 253a materials.

We give a pedagogical introduction to algebraic quantum field theory (AQFT), with the aim of explaining its key structures and features. Topics covered include: algebraic formulations of quantum theory and the GNS representation theorem, etc.

The purpose of this review is to bridge the gap between a standard course in quantum field theory and recent fascinating developments in the studies of on-shell scattering amplitudes. We build up the subject from basic quantum field theory...

The course will introduce Quantum Field Theory (QFT) by bringing together concepts from classical Lagrangian and Hamiltonian mechanics, quantum mechanics and special relativity. We will also introduce string theory as a simple two-dimensional QFT.
