Student advisingAnton Iliashenko (NSERC-Undergraduate Student Research Assistant) Spring 2019. (co-supervised with Spiro Karigiannis) Project title: "Flows of metrics induced from mean curvature flow"
Project abstract: The mean curvature flow is a flow of an isometrically immersed submanifold M inside an ambient Riemannian manifold X in the direction of the mean curvature vector field. The Ricci flow is an i ntrinsic flow of a metric on a Riemannian manifold M in the direction of (minus) the Ricci tensor. Let M be a Riemannian manifold and consider it as the zero section inside one of its tensor bundles X, such as the cotangent bundle X = T* M or the real canonical bundle X = Λn (T* M) where n = dim(M). Using the Levi-Civita connection of M, there is a canonical Riemannian metric induced on X, which makes the zero section isometrically immersed. Therefore one can evolve M inside X by the mean curvature flow. For small time, this evolution Mt will be canonically diffeomorphic to M using the exponential map on the mean curvature vector field. Pulling back via this diffeomorphism, the mean curvature flow of M in X thus induces an intrinsic flow of metrics on M.
The natural question is: what is this induced flow of metrics? If it is the Ricci flow, this gives a new interesting characterization of Ricci flow. If it is not the Ricci flow, this could be a new interesting canonical flow of metrics. Moreover, in the case when X = T* M, the zero section is Lagrangian, and mean curvature flow preserves the Lagrangian condition. The Lagrangian mean curvature flow is well-behaved. Similarly, when X = Λn (T* M), then M is a hypersurface in X. The hypersurface mean curvature flow is also well-behaved.
