This is a reminder for the next session of the "Sub-Riemannian
Seminars" (Fri May 21, 16:00-17:00 Paris time (CEST), on Zoom).

The speaker will be Federica Dragoni (Cardiff University), who will give
a talk with the title: "Asymptotics for optimal controls for
horizontal mean curvature flow".


Abstract:
The solutions to surface evolution problems like mean curvature flow
can be expressed as value functions of suitable stochastic control
problems, obtained as limit of a family of regularised control
problems. The control-theoretical approach is particularly suited for
such problems for degenerate geometries like the Heisenberg group. In
this situation a new type of singularities absent for the Euclidean
mean curvature flow occurs, the so-called characteristic points. In
this talk I will investigate the asymptotic behaviour of the
regularised optimal controls in the vicinity of such characteristic
points.
Join work with Nicolas Dirr and Raffaele Grande.
