       Title:  Controlling Regularized Conservation Laws via Entropy-Entropy Flux Pairs

       Wuchen Li, University of South Carolina

Abstract:    In this talk, we study a class of variational problems for regularized conservation laws with Lax's entropy-entropy flux pairs. We first introduce a modified optimal transport space based on conservation laws with diffusion. Using this space, we demonstrate that conservation laws with diffusion are "flux-gradient flows". We next construct variational problems for these flows, for which we derive dual PDE systems for regularized conservation laws. Several examples, including traffic flow, Burgers' equation, and barotropic compressible Navier–Stokes equations, are presented. Incorporating both primal-dual hybrid gradient algorithms and monotone schemes, we successfully compute the control of conservation laws. This is based on a joint work with Siting Liu and Stanley Osher.
