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.
