Pseudo Ricci symmetric real hypersurfaces of a complex projective space
Pseudo Ricci symmetric real hypersurfaces of a complex projective space are classified and it is proved that there are no pseudo Ricci symmetric real hypersurfaces of the complex projective space CPn for which the vector field ξ from the almost contact metric structure (φ, ξ, η, g) is a principal curvature vector field.

متن کاملReal Hypersurfaces of a Complex Projective Space Satisfying Certain Conditions
The objective of the present paper is to study real hyper surfaces of a complex projective space with generalized recurrent second fundamental tensor and it is shown that such type real hyper surface exist. Also, we study real hyper surfaces of a complex projective space with generalized recurrent Ricci tensor. It is proved that a real hyper surfaces of complex projective space is generalized R...
متن کاملReal Hypersurfaces of a Complex Space Form
In this paper, we show that an n-dimensional connected noncompact Ricci soliton isometrically immersed in the at complex space form (C n+1 2 ; J; h; i), with potential vector eld of the Ricci soliton is the characteristic vector eld of the real hypersurface is an Einstein manifold. We classify connected Hopf hypersurfaces in the at complex space form (C n+1 2 ; J; h; i) and also obtain a ch...
متن کاملReal Hypersurfaces in a Euclidean Complex Space Form
Let M be an orientable connected and compact real hypersurface of the complex space form C(n+1)/2. If the mean curvature α and the function f = g(Aξ, ξ) of hypersurface M satisfy the inequalityn2α2 ≤ (n2 − 1)δ + f 2, where ξ is the characteristic vector field,A is the shape operator and (n− 1)δ is the infimum of the Ricci curvatures of hypersurface M , then it is shown that α is a constant and ...
