On contact conformal curvature tensor in LP-Sasakian manifolds

open access: yesBibechana, 2017
The purpose of the present paper is to study the contact conformal curvature tensor in LP-Sasakian manifolds. Some properties of contact conformally flat, ξ -contact conformally flat and contact conformally semi-symmetric LP-Sasakian manifolds are ...

On a class of \(SP\)-Sasakian manifold

open access: yes, 1990
A para-Sasakian manifold, i.e. a special paracontact manifold with a structure \((\varphi,\xi,\eta,g)\), is called special para-Sasakian (shortly \(SP\)-Sasakian) if the 1-form \(\eta\) satisfies the equation \(\nabla d\eta=\varepsilon(-g+d\eta\otimes d\eta)\), \(\varepsilon=\pm 1\).
