Abstract：  The optimal transportation problem was introduced by Monge in 1781. Since then the problem has been extensively studied and general costs are allowed. But for Monge's orignal cost, very little is known about the regularity. In this talk, we discuss the regularity in Monge's problem, and in particular show that, in two dimensional case, the optimal mapping is continuous. The talk is based on joint works with F. Santambrogio and X.-J. Wang.
