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.

An elementary introduction to black holes in supergravity and string theory. The focus is on BPS solutions in four- and higher-dimensional supergravity and string theory. Basic ideas are explained in detail, including exercises with solutions.

The text covers the basic concepts of modern string theory: covariant and light-cone quantisation of bosonic and fermionic strings, geometry and topology of string world-sheets, vertex operators and string scattering amplitudes, etc.
