SUMMARY:On the consistency of a BMO-type scheme and convexity preservation
for a fractional mean curvature flow -
DESCRIPTION:In this talk we define a class of mean curvature flows\, where
the curvature is replaced by its non-local conterpart\, which will be intr
oduced as well. We then introduce an appropriate Bence-Merriman-Osher (BMO
) approximation scheme for the flow\, showing that it is consistent even i
f we work in an anisotropic setting. This\, together with some tools borro
wed 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 la
tter fact\, quite surprisingly\, applies as well in a large class of geomt
ric flows. The talk is based on a joint work with A. Chambolle and M. Nova
