Schroedinger Lecture 2016
Ultraviolet and infrared divergences in string theory
Date: Monday, May 2, 2016
Time: 16.45 h (followed by an apéro)
Superstring theory is known to be free from ultraviolet divergences but suffers from the usual infrared divergences that occur in quantum field theories. After briefly reviewing the origin of ultraviolet finiteness of superstring theory we describe recent progress towards the understanding of infrared divergences in superstring theory.
