Generalized curvature tensor and the hypersurfaces of the Hermitian manifold for the class of Kenmotsu type
This paper determined the components of the generalized curvature tensor for
the class of Kenmotsu type and established the mentioned class is
{\eta}-Einstein manifold when the generalized curvature tensor is flat; the
converse holds true under suitable conditions. It also introduced the notion of
generalized {\Phi}-holomorphic sectional (G{\Phi}SH-) curvature tensor and thus
found the necessary and sufficient conditions for the class of Kenmotsu type to
be of constant G{\Phi}SH-curvature. In addition, the notion of
{\Phi}-generalized semi-symmetric was introduced and its relationship with the
class of Kenmotsu type and {\eta}-Einstein manifold established. Furthermore,
this paper generalized the notion of the manifold of constant curvature and
deduced its relationship with the aforementioned ideas. It finally showed that
the class of Kenmotsu type exists as a hypersurface of the Hermitian manifold
and derived a relation between the components of the Riemannian curvature
tensors of the almost Hermitian manifold and its hypersurfaces.
