摘要
In this paper, we prove that the ∗-Ricci tensor of a real hypersurface in complex projective plane ℂ P 2 or complex hyperbolic plane ℂ H 2 is cyclic parallel if and only if the hypersurface is of type (A). We find some three-dimensional real hypersurfaces having non-vanishing and non-parallel ∗-Ricci tensors which are cyclic parallel.
