本文在凸边界且非负Ricci曲率的三维流形中,对指标为一的自由边界极小曲面或稳定的自由边界常平均曲率曲面,在Jacobi算子第一Dirichlet特征值非负时,给出亏格和边界分量数的界,并应用于三维正规齐次空间的严格凸区域,得到强拓扑限制。

我们研究了在具有凸边界和非负Ricci曲率的Riemannian三维流形中,作为自由边界极小曲面且指标为一,或作为自由边界常平均曲率曲面且稳定的曲面,在其Jacobi算子的第一Dirichlet特征值非负的条件下,给出了其亏格和边界分量数的界。作为应用,我们在三维正规齐次空间的紧致严格凸区域中,建立了此类曲面的强拓扑限制。
英文摘要
We find bounds for the genus and for the number of boundary components of a surface that is either index one as a free boundary minimal surface or stable as a free boundary constant mean curvature surface in a Riemannian three-manifold with convex boundary and non-negative Ricci curvature, provided the first Dirichlet eigenvalue of its Jacobi operator is non-negative. As an application, we establish strong topological restrictions on such surfaces in compact strictly convex domains of three-dimensional normal homogeneous spaces.
