INRIA PARIS 10h30 Salle JLL Francis Bach (SIERRA) [SLIDES] Title: Submodular Functions: from Discrete to Continous Domains Résumé: Submodular set-functions have many applications in combinatorial optimization, as they can be minimized and approximately maximized in polynomial time. A key element in many of the algorithms and analyses is the possibility of extending the submodular set-function …

Paris-Dauphine) Titre: Gradient approximation of the Monge problem Résumé: We investigate the approximation of the L^1-optimal transport problem with a vanishing Dirichlet energy \eps\int|DT|^2. We study the \Gamma-convergence as \eps goes to 0, by showing a density result, among the set of transport maps between …
