SUMMARY:A new point of view on (crystalline) mean curvature flows - Antoni

DESCRIPTION:In a joint work with M. Morini (Parma)\, M. Ponsiglione (Roma 
 I)\, we propose a new (elementary) definition for sub and super flows of h
 ypersurfaces by anisotropic mean curvature\, for which existence and compa
 rison results can be proved by relatively classical techniques. The method
  assumes very little smoothness and allows to extend standard existence an
 d uniqueness results to the crystalline curvature flow with "natural" mobi
 lity. The crystalline curvature flow is a formal "gradient flow" of a peri
 meter which is measured with a surface tension both nonsmooth and non elli
 ptic.
