摘要：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.
