报告摘要： Isometric immersion is an important problem in geometry.The Gauss-Codazzi equations for isometric immersions of surfaces will be considered. The connections with fluid dynamics will be shown.  Various approaches and recent results on global solutions for the hyperbolic problem with negative Gauss    curvatures will be presented. In particular, the global smooth isometric immersion of surfaces with slow decay rates for   the curvatures will be discussed.
