Abstract

We aim to classify the real hypersurfaces M in a Kaehler complex space form Mn(c) satisfying the two conditions φl=lφ, where l=R(,ξ)ξ and φ is the almost contact metric structure of M, and (ξl)X= ω(X)ξ, where where ω(X) is a 1-form and X is a vector field on M. These two conditions imply that M is a Hopf hypersurface and ω = 0.
