OVERVIEW

Lectures are held in English or Italian, at the students' choice. The course is addressed to students in mathematics. but it can also be also attended by students in physics.

AIMS AND CONTENT

LEARNING OUTCOMES

The purpose of the teaching is to provide an introduction to gauge theories. In particular, after having introduced the necessary notions of differential geometry (theory of connections on vector and principal bundles, Hodge theory), we will deal with some salient aspects of Yang-Mills theories on 4-dimensional Riemannian manifolds, arriving at the study of the structure local of the instanton module space.

PREREQUISITES
