题目：The plane logarithmic Minkowski problem

摘要：

    The classical Minkowski’s existence theorem due to Minkowski and Aleksandrov characterizes the surface area measure   of a convex body  in   More precisely, it solves the Monge-Ampere equation on the unit sphere   where a convex body  with   boundary provides a solution if   for the support function   of    The logarithmic Minkowski problem  was posed by Firey in his 1974 seminal paper.  It seeks to characterize the cone volume measure   of a convex body  containing the origin o. The logarithmic Minkowski problem   is a challenging problem in convex geometry and receives much attention since 2012.

   In this talk, we will present our very recent work on the logarithmic Minkowski problem. We prove the existence of solutions to the logarithmic Minkowski problem for quadrilaterals, and characterize the numbers of solutions completely. 

This talk is based on the joint work with Liu Yude, Lu Xinbao and Sun Qiang.
