描述In this thesis, we study the regularity of optimal transport maps and its applications to the semi-geostrophic system. The first two chapters survey the known theory, in particular there is a self-contained proof of Brenier’ theorem on existence of optimal transport maps and of Caffarelli’s Theorem on Holder continuity of optimal maps. In the third and fourth chapter we start investigating Sobolev regularity of optimal transport maps, while in Chapter 5 we show how the above mentioned results allows to prove the existence of Eulerian solution to the semi-geostrophic equation. In Chapter 6 we prove partial regularity of optimal maps with respect to a generic cost functions (it is well known that in this case global regularity can not be expected). More precisely we show that if the target and source measure have smooth densities the optimal map is always smooth outside a closed set of measure zero.

An overview on optimal transportation, ? (Y) and a .: . × . → ? we look for a map . such that .. = .. and that minimize . In general, there could be no solution to the above problem both because the class of admissible maps is empty (for instance in the case in which μ is a Dirac mass and . is not) or because the infimum is not attained (see [95, Example 4.9]).

,The Monge-Ampère equation,a proof of Caffarelli .. regularity theorem [18, 20]. Many of the tools developed in this Chapter will play a crucial role in the proof of the Sobolev regularity in Chapter 3. In the last Section we show, without proofs, how to build smooth solutions to the Monge-Ampère equation throughout the method of continuity.

Partial regularity of optimal transport maps,The goal of this chapter (based on a joint work with Alessio Figalli [43]) is to prove partial regularity of optimal transport maps under mild assumptions on the cost function c and on the densities f and g, Theorems 6.1 and 6.2 below.
