DESCRIPTION:Speaker: Tim Laux\nhosted by Julian Fischer\nAbstract: The thre
 sholding scheme\, also known as diffusion generated motion\, is an efficie
 nt numerical algorithm for computing mean curvature flow (MCF). In this ta
 lk I will briefly discuss the case of hypersurfaces\, and then present our
  first convergence analysis in the case of codimension two. The proof is b
 ased on a new generalization of the minimizing movements interpretation fo
 r hypersurfaces (Esedoglu-Otto '15) by means of an energy that approximate
 s the Dirichlet energy of the state function. As long as a smooth MCF exis
 ts\, we establish uniform energy estimates for the approximations away fro
 m the smooth solution and prove convergence towards this MCF. The result r
 elies in a very crucial manner on a new sharp monotonicity formula for the
  thresholding energy. This is joint work with Aaron Yip (Purdue).
