Description

Here we are concerned with the optimal transport of masses from one location to the other, where the optimality depends upon the context. The problems appear in several areas: economics, probaility, optimition, meteorology and computer graphics. In the last decade, researchers discovered strong connections between these equations and nonlinear PDEs, for example, when the cost function is quadratic the optimal transportation is intimately related to the Monge-Ampere equation. The Wasserstein distance appears in the formulation of several results for evoltuion equations arising from optimal transportation. NOTE: This workshop is to be held at the International House on the UC Berkeley campus, at 2299 Piedmont Avenue, except for the Tuesday session, which will be held at the Lawrence Berkeley National Laboratory. On site registration for the workshop will start at 8:30 AM Monday and end at 3:30 PM Monday.
