Ricci operator in a Hopf real Hypersurfaces of complex space form
We initiate the study of real hypersurface of a complex space form and it is proved that Lie parallelism of the Ricci operator in the direction of ?, locally symmetric Ricci operator in a real hypersurface of a complex space form reduce the hypersurface to Hopf hypersurface. � 2020 IOP Publishing Ltd.

Generalized complex space forms
In this paper, we find an eigen value of Ricci operator corresponding to scalar curvature r of a generalized complex space form and we give conditions for the existence of a generalized complex space form. Copyright � Deanship of Research and Graduate Studies, Yarmouk University, Irbid, Jordan.
Some curvature properties of kenmotsu manifolds with schouten-van kampen connection
