SUMMARY: (...): On the consistency of a BMO-type scheme and convexity prese
 rvation for a fractional mean curvature flow
DESCRIPTION:: In this talk we define a class of mean curvature flows\, wher
 e the curvature is replaced by its non-local conterpart\, which will be in
 troduced as well. We then introduce an appropriate Bence-Merriman-Osher (B
 MO) approximation scheme for the flow\, showing that it is consistent even
  if we work in an anisotropic setting. This\, together with some tools bor
 rowed from the theory of convex bodies\, allow us to show that the scheme\
 , and thus the flow\, is convexity preserving. The technique to show this 
 latter fact\, quite surprisingly\, applies as well in a large class of geo
 mtric flows. The talk is based on a joint work with A. Chambolle and M. No
 vaga.http://cvgmt.sns.it/person/973/
