报告题目： $C^{1, \alpha}$ isometric extension
报告摘要： Given an isometric immersion into Euclidean space $\R^q$ of a codimension one submanifold of an $n$-dimensional Riemannian manifold ($q\geq n+1, n\geq2$), we obtain a $C^{1, \alpha}$ isometric extension of such immersion with $0\leq\alpha<\frac{1}{n(n+1)+1}$ through convex integration. This is a joint work with Prof. Laszo Szekelyhidi Jr.

报告题目：Large-time Behavior of Solutions for the Compressible Navier-Stokes Equations with  Large Perturbation.
报告摘要：In this talk, we concern with the large-time behavior of solutions to the initial boundary value problem of the compressible Navier-Stokes system. We show that the combination of transonic BL-solution, viscous contact wave with rarefaction waves for the non-isentropic polytropic gas is stable under large initial perturbation, provided the strength of the combination waves is suitably small.
