报告题目: Stable capillary hypersurfaces supported on a horosphere in the hyperbolic space
报告人: 国金宇(清华大学)
摘要:In this talk, we study a stability problem of free boundary hypersurfaces, and also capillary ones whose boundary supported on a horosphere in hyperbolic space. We prove that umbilical hypersurfaces are only stable immersed capillary hypersurfaces whose boundary supported on a horosphere. Using the same method, we show that a totally geodesic hyperplane is only stable immersed type-II hypersurface whose boundary supported on a horosphere.This is a joint work with Prof.Guofang Wang and Prof.Chao Xia.
