The interior $C^2$ estimate for Monge-Ampere equation in dimension two

2维梦日—安培方程的$C^2$内估计

The interior $C^2$ estimate for admissible solutions of $\sigma_2(D^2 u)=f>0$ is a longstanding and important problem. In this talk, we introduce a new auxiliary function, and establish a new proof of the interior $C^2$ estimate in dimension two, which was firstly proved by Heinz [J. Analyse Math., 1959]. This is a joint work with Fei Han and Qianzhong Ou.
