An Introduction to String Theory
by James Bedford
Publisher: arXiv 2011
Number of pages: 101
The text provides an introduction to string theory, focusing on the Bosonic string, but treating the superstring as well. A number of appendices on more advanced topics are also provided, including an introduction to orientifolds in various brane configurations. A background in quantum field theory and general relativity is assumed.

This text provides some historical background and then reviews developments in string theory over the last twenty-five years. Both perturbative and non-perturbative approaches are surveyed and their impact on how we view quantum gravity is analysed.

Basic aspects of non-perturbative string theory are discussed. The topics include test of duality symmetries based on the analysis of the low energy action and the spectrum of BPS states, relationship between different duality symmetries, etc.

These lecture notes provide a detailed introduction to the bosonic string and conformal field theory. The text is aimed at beginning graduate students. It assumes a working knowledge of quantum field theory and general relativity.
