Existence and uniqueness for crystalline mean curvature flows with general mobilities – Marcello Ponsiglione (Universita’ di Roma La Sapienza)

Venue

Sala Seminari (Dip. Matematica).

Abstract

In this seminar we will discuss weak formulations for crystalline mean curvature flows, providing existence and uniqueness of the geometric evolution up to fattening. In particular, we show that the Almgren-Taylor-Wang scheme starting from any given initial set converges, up to fattening, to a unique flat flow. These results are in collaboration with A. Chambolle, M. Morini and M. Novaga.
