Geometry and Topology Seminar ——A family of Monge-Ampère type operators converging to sigma_k, and their Minkowski problems
地点：Room 1114, Sciences Building No. 1
Abstract: We introduced a new family of translation invariant geometric measures arising from Integral Geometry of convex bodies. These measures are related to a family of new Monge-Ampère type operators converging to a sigma_k operator. The Minkowski problems for these new measures are proposed and attacked. This is joint work with Erwin Lutwak, Deane Yang, and Gaoyong Zhang.
