A note about almost contact metric hypersurfaces axioms for almost Hermitian manifolds
In the present note, we discuss some problems related to almost contact
metric hypersurfaces axioms for almost Hermitian manifolds. In particular,
we select some special types of almost contact metric hypersurfaces
axioms for almost Hermitian manifolds. We mark out the axioms
consisting of the conditions for the almost contact metric structure on the
hypersurface of an almost Hermitian manifold to belong to a special class
(for example, to the class of Sasakian or quasi-Sasakian structures). We
also mark out the axioms that are related to the second fundamental form
of the immersion of the almost contact metric hypersurface into an almost
Hermitian manifold
