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

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…

On the speed of propagation for stochastic Hamilton-Jacobi equations – Paul Gassiat (Université Paris Dauphine)

We study the speed of propagation of initial data for Hamilton-Jacobi equations with multiplicative rough (typically stochastic) time dependence. We first show that, in contrast with the classical (deterministic) case, in general this speed may be…
