题目:Nonlinear Dynamics of Relativistic Strings/membranes
摘要:This talk concerns the motion of relativistic strings/membranes in physical space-times, this kind of motion is related to the theory of extremal surfaces/submanifolds in these space-times. We first study the equations for relativistic strings/membranes moving in these space-time and then analyze some interesting properties enjoyed by these equations. Based on this, we prove some global existence theorems on smooth solutions. We also describe some of the discoveries that have been done about it, and some unresolved questions.
