报告题目：Smooth solutions to the degenerate hyperbolic Gauss-Codazzi system

报告摘要：In this talk, I will introduce some results on the study of the degenerate hyperbolic Gauss-Codazzi system. We construct a local smooth solution on the region with negative Gauss curvature for the Gauss-Codazzi system by assigning appropriate boundary data on the given zero Gauss curvature curve. Moreover, the uniform regularity of the solution up to the zero Gauss curvature curve is also discussed. The main tool is the characteristic decomposition technique in terms of the fluid dynamic framework.
