报告题目：A Liouville's theorem for some Monge-Ampère type equations

摘要：In this talk we study a Monge-Ampère type equation that interpolate the classical 2-Yamabe problem in conformal geometry and the 2-Hessian equation in dimension 4.This is a joint work with Hao Fang and Biao Ma.

报告题目：Regularity of subelliptic harmonic maps with values into metric spaces of nonpositive curvature

摘要：We present a result of Holder continuity of a harmonic map from a domain of a sub-Riemanian manifold into a locally compact manifold with nonpositive curvature, and more generally into a non- positively curved metric space in the Alexandrov sense. This is a joint work with Prof. Jost and Prof. Li-Jost.

报告人简介：Gui Yaoting, obtain his doctorate degree from USTC in June 2022. His main interest is nonlinear analysis on manifolds, especially in the analysis on singular space, such as conical manifolds and degenerate elliptic operator. He visits the Max Planck Institute from 2022.03 to 2022.07, and he has been offered a postdoc fellowship in BICMR.
