Topics in Equilibrium Transportation Galichon, Alfred


Motivated by problems from economics, I will present a framework for "Equilibrium Transportation", which embeds the Monge-Kantorovich "Optimal Transportation" problem, but is more general, and more natural in some applications. In the discrete case, this framework allows for a unified description of Gale and Shapley's stable marriage problem, as well as Koopmans and Beckmann's optimal assignment problem. I will sketch the link with "Galois connections" and recent results by Trudinger on the local theory of prescribed Jacobian equations. I will then turn to computational issues, and will present an extension of the Iterated Projections algorithm that allows for efficient approximate computation of these problems.
