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.

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.
