DESCRIPTION:Title: <a href="https://researchseminars.org/talk/iccm2020/79/
 ">Ancient solution of mean curvature flow of arbitrary codimension</a>\nby
  Li Lei/雷力 as part of ICCM 2020\n\n\nAbstract\nIn this talk\, we will 
 discuss rigidity problem of ancient solutions of the mean curvature flow w
 ith arbitrary codimension in space forms. We first prove that under certai
 n sharp pointwise curvature pinching condition the ancient solution in a s
 phere is either a shrinking spherical cap or a totally geodesic sphere. Th
 en we show that under certain pointwise curvature pinching condition the a
 ncient solution in a hyperbolic space is a family of shrinking spheres. We
  also obtain a rigidity result for ancient solutions in a nonnegatively cu
 rved space form under an integral curvature pinching condition. This is jo
 int work with Prof. H. W. Xu and Prof. E. T. Zhao.\n
