Venue: Room 201 Lecture Hall

abstract:We introduce a new method to obtain Harnack inequalities for extrinsic curvature?ows such as the mean curvature?ow and more general fully nonlinear?ows. For example, this method allows us to deduce Harnack inequalities for the mean curvature?ow in locally symmetric (Riemannian or Lorentzian) Einstein spaces, for?ows with convex speeds in the De Sitter space and for the Gauss curvature?ow in Minkowski space. (Joint work with Paul Bryan and Mohammad Ivaki).
