DESCRIPTION:On the classification of ancient solutions to curvature flows o
 n the sphere. \n\nAn ancient solution to a curvature flow is a solution th
 at exists backwards in time forever. In this talk\, I will discuss the cla
 ssification of ancient solutions to curvature flows on the sphere. I will 
 prove that the sphere exhibits a very strong rigidity: any ancient solutio
 n of a curvature flow which satisfies a backwards in time uniform bound on
  mean curvature must be stationary or a family of shrinking geodesic spher
 e. The main tools are geometric\, employing the maximum principle\, a rigi
 dity result in the sphere and an Alexandrov reflection argument.\n
