Abstract

Let M be a real hypersurface in a complex space form M<sub>n</sub>(c), c &#x2260; 0. In this paper, we prove that if (&#x2207;<sub>X</sub>&#x03D5;)Y + (&#x2207;<sub>Y</sub>&#x03D5;)X = 0 holds on M, then M is a Hopf hypersurface, where &#x03D5; is the tangential projection of the complex structure of M<sub>n</sub>(c). We characterize such Hopf hypersurfaces of M<sub>n</sub>(c).
