Introduction to String Theory
by Thomas Mohaupt
Publisher: arXiv 2002
Number of pages: 78
The aim of these notes is to give an introduction to string theory for students and interested researches. No previous knowledge of string theory is assumed. The focus is on gravitational aspects and we explain in some detail how gravity is described in string theory in terms of the graviton excitation of the string and through background gravitational fields.

Introduction to tachyon condensation in Witten's cubic bosonic open string field theory. We use both the low-energy Yang-Mills description and the language of string field theory to explain the problem of tachyon condensation on unstable D-branes.

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.
