On a class of para-Sasakian manifolds

open access: yes, 2005
The author investigates (under a conformality condition) the Weyl-pseudosymmetric para-Sasakian manifolds which are the extended class of Weyl-semisymmetric para-Sasakian manifolds.

ON SUBMANIFOLDS OF PARA-SASAKIAN MANIFOLDS

open access: yesJP Journal of Geometry and Topology, 2016
Summary: Studying in submanifolds of para-Sasakian manifolds, we obtain that (1) semi-parallel and 2-semi-parallel invariant submanifolds are totally geodesic, (2) necessary and sufficient conditions for the integrability of distributions and (3) some characterizations for submanifolds to be semi-invariant.

Some Conditions on Trans-Sasakian Manifolds to Be Homothetic to Sasakian Manifolds

open access: yesMathematics, 2021
In this paper, we study 3-dimensional compact and connected trans-Sasakian manifolds and find necessary and sufficient conditions under which these manifolds are homothetic to Sasakian manifolds.

Special para-Sasakian manifolds and concircular transformations

TRU Mathematics, 1984
The authors continue the study of the special para-Sasakian manifolds. More precisely, they consider the D-conformal change which corresponds to the concircular transformation in the integral manifold of the Pfaffian equation \(\eta =0\) and prove that a certain tensor field \(U^ h_{kji}\) on special para-Sasakian manifolds is invariant under this D ...

On exact 2-para Sasakian manifolds

Rendiconti del Circolo Matematico di Palermo, 1999
In [Tensor, New Ser. 42, No. 1, 42-54 (1985; Zbl 0578.53027)] the reviewer defined the notion of an almost \(r\)-paracontact manifold of P-Sasakian type. In this paper the authors study the geometry of a special case, an exact 2-para Sasakian manifold.
