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.

Leonard Susskind, one of the co-inventors of the Holographic Principle as well as one of the founders of String theory, develops and explains these concepts. This well-planned, stimulating and provocative book can be enthusiastically recommended.
A short introduction to superstring theory. From the table of contents: Classical Theory of String; Quantization; Supersymmetry and Superstring; Compactification; Types of Superstring Theory; M-theory; Problems and Future Development.

We review cosmological inflation and its realization in quantum field theory and string theory. We describe two intertwined approaches to the physics of inflation: from the bottom up in effective field theory, and from the top down in string theory.
