摘 要：I will talk about the rigidity of contact stationary Legendrian (CSL) submanifolds in the unit sphere. We prove some optimal rigidity results of closed CSL submanifolds and obtain a new characterization of the Calabi torus in the unit sphere.

摘 要：In this talk, we will introduce the constant rank theorem, a technique to study the convexity of solutions to PDEs. In particular, the constant rank theorem of spacetime level sets of heat equation, a joint work with Xinan Ma and Paolo Salani, will be particularly discussed.
