Harnack inequalities for evolving hypersurfaces
6 mars 2017 @ 14:00 – 15:00 – We introduce a new method to obtain Harnack inequalities for extrinsic curvature flows such as the mean curvature flow and more general fully nonlinear flows. For example, this method allows us to deduce Harnack inequalities for the mean curvature flow in locally symmetric (Riemannian or Lorentzian) Einstein spaces, for flows with convex speeds in the […]
