B2246 - INTRODUCTION TO STRING THEORY

Conoscenze e abilità da conseguire

This course gives a comprehensive introduction to the basic concepts of string theory. At the end of the course the students will gain a solid knowledge of the bosonic string, superstring theory, spacetime effective actions, string compactifications, D-branes and string dualities, holography. In particular they will acquire the tools necessary to understand modern developments of string theory and its connections with quantum field theory, low energy phenomenology and cosmology, supersymmetric gauge theories and pure mathematics.
