The lectures will cover classical and recent results on the Monge-Kantorovich theory of optimal transport. In particular we focus on the problem of the existence of optimal transport maps and on the different formulations of the problem, due to Kantorovich, Benamou-Brenier and Evans-Gangbo. In the case of distance cost functions we also discuss the role of the so-called transport density and we analyze its regularity properties. We discuss also some applications of the theory to Shape Optimization and Partial Differential Equations.
