String Theory seminar - Davide Bufalini  Seminar

Abstract: I will deliver a pedagogical introduction to the Wess-Zumino-Witten model, focusing mainly on geometric aspects of it. We will start by recalling what a non-linear sigma model is and then we will understand the properties and structure behind the WZW model by means of basic differential-geometric concepts that will be very natural in this context. We will also discuss the idea behind the gauging of the WZW model and start to understand its importance for the Microstate Geometries programme.
