摘要：The time-like extremal surface equations are the hyperbolic counterpart of the famous minimal surface equations, which are important in geometry and physics. In this talk, I will introduce the research history and the main results obtained in this topic. In particular, I want to introduce our recent results on the globally smooth solutions with large energy, including the large perturbations of the travelling wave to the relativistic string equations and the relativistic membrane equations with short-pulse initial data. This talk is based on several joint works with Prof. Jinhua Wang.
