Séminaire d'AnalyseMean curvature flow with obstacles
lundi 03 juin 2013 11:00 - Tours - Salle 1180 (Bât E2)
I will consider the evolution of fronts by mean curvature in the presence of obstacles. In particular, I will introduce a notion of weak solution to the flow obtained a variational implicit scheme, and discuss an adaptation of the viscosity theory to this setting. Eventually, assuming the regularity of the obstacles, I will show existence and uniqueness of regular solutions for short times.
