Colding-Minicozzi Entropies in Cartan-Hadamard Manifolds

Speaker: Jacob Bernstein, John Hopkins University

Location: Warren Weaver Hall 512

We discuss a new family of functionals on submanifolds of
Cartan-Hadamard manifolds that generalize the Colding-Minicozzi entropy
of submanifolds of Euclidean space. These quantities  are monotone
under mean curvature flow under natural conditions. As a consequence,
we obtain sharp lower bounds on them for certain closed hypersurfaces
and observe a novel rigidity phenomenon.  This is joint work with A.
