报告摘要:In this talk, we shall introduce our recent work on self-shrinkers and its related topics. Firstly, we study the mean curvature flow of hyper-Lagrangian manifolds L^{2n} in hyper-kaehler manifolds M^{4n}. When n>1, we proved that such hyper-Lagrangian manifolds must be complex Lagrangian. So we only need to consider the case n=1, by the observation that any surface in 4-dim hyper-Kaehler manifolds is hyper-Lagrangian automatically and the complex phase map of self-shrinking surfaces is a generalized harmonic map, we showed that any complete proper self-shrinking surfaces in R^4 with the image of the complex phase map contained in S^2 omit the closed half of the great circle must be plane. Based on this rigidity and the blow up technique of mean curvature flow, we conclude that the corresponding MCF from closed surfaces with the image of the complex phase map contained in S^2 omit the closed half of the great circle does not de
