French mathematician who established the polar-factorization approach to optimal transport and its links with fluid mechanics.
Yann Brenier made foundational contributions to optimal transport. His polar factorization theorem decomposes a map into a measure-preserving part and the gradient of a convex function, giving a geometric route to transport maps. His ideas also connect optimal transport with incompressible Euler flows and kinetic equations.
