We show that minimal action exists and satisfies a compressible Euler equation in weak sense. Moreover, we prove that both Cauchy and resolvent formulations of the associated Hamilton-Jacobi equation, in the space of probability measures, are well posed. In addition to technical issues in optimal control and modern mass transport theories, there are two key arguments which involves relaxation and regularization in formulation of the problem. They are both rooted in questions from probability. In particular, from a large deviation theory point of view,the regularization we introduced is a natural way to define entropic solution in path space. This is a joint work with Truyen Nguyen.Date: Monday, August 30, 2010Time: 5:00 pmLocation: Wean Hall 8220Submitted by:  Gautam Iyer
