摘要: I will talk about our recent works on convex hypersurfaces in hyperbolic space.I will show that the end at boundary of the infinity of an embedded hypersurface with positive Ricci curvature has one or two points. We will also show that an immersed hypersurface with nonnegative sectional curvature has to be embedded.
