A Constrained Mean Curvature Flow On Capillary Hypersurface Supported On Totally Geodesic Plane

Abstract

We prove a new Minkowski type formula for capillary hypersurfaces supported on totally geodesic hyperplanes in hyperbolic space. It leads to a volume-preserving flow starting from a star-shaped initial hypersurface. We prove the long-time existence of the flow and its uniform convergence to a $\theta$-totally umbilical cap. Additionally, we establish that a $\theta$-totally umbilical cap is an energy minimizer for a given enclosed volume.

All comments are welcome
