设M是非平坦复空间形式中具有几乎切触度量结构的真实的超曲面。本文证明了:如果结构Jacobi算子与结构张量和Ricc张量S交换,则M是一个Hopf超曲面,只要M的平均曲率为常数或为常数.
Let M be a real hypersurface with almost contact metric structure in a nonflat complex space form . In this paper, we prove that if the structure Jacobi operator commutes with both the structure tensor and the Ricc tensor S, then M is a Hopf hypersurface in provided that the mean curvature of M is constant or is constant.
