报告题目：C1,1/3−very weak solutions to the two dimensional Monge–Ampère equation
报 告 人：曹文涛，首都师范大学
报告摘要：This talk is about very weak solutions to Monge-Ampere equations. For any θ<1/3 , we show that very weak solutions to the two-dimensional Monge–Ampère equation with regularity C1,θ are dense in the space of continuous functions. This result is shown by a convex integration scheme involving a subtle decomposition of the defect at each stage. The decomposition diagonalizes the defect and, in addition, incorporates some of the leading-order error terms of the first perturbation, effectively reducing the required amount of perturbations to one. This talk is based on a joint work with Prof. Jonas Hirsch and Dominika Inauen.
