摘要

In this paper, we prove a Heintze-Karcher type inequality for capillary hypersurfaces supported on various hypersurfaces in hyperbolic space. The equality case occurs only for capillary hypersurfaces that are totally umbilical. Then we apply this result to prove the Alexandrov type theorem for embedded capillary hypersurfaces in the hyperbolic space. In addition, we prove some other rigidity results for capillary hypersurfaces supported on a totally geodesic plane in the hyperbolic space.
