报告摘要：Stable Bernstein problem asks whether two-sided stable minimal hypersurface must be hyperplane. Stability can be also defined on constant mean curvature (CMC) hypersurfaces. A similar question is asked by do Carmo on CMC hypersurfaces that whether stable ones must be “minimal” in general manifolds. In this talk, we will discuss some results about this question, especially in Euclidean space and hyperbolic space. In particular, we show that under certain assumption stable ones in hyperbolic space with mean curvature no less than one must have mean curvature one. The idea is the application of mu-bubble and harmonic function theory.
