The main purpose of the present paper is to study the geometry of screen transversal lightlike submanifolds and radical screen transversal lightlike submanifolds and screen transve…
Remarks on almost -Ricci solitons in -para Sasakian manifolds
Adara M. Blaga, Selcen Yuksel Perktas
We consider almost -Ricci solitons in -para Sasakian manifolds satisfying certain curvature conditions. In the gradient case we give an estimation of the Ricci cu…
-Ricci solitons in -almost paracontact metric manifolds
Adara Monica Blaga, Selcen Yüksel Perktaş, Bilal Eftal Acet +1
The object of this paper is to study -Ricci solitons on -almost paracontact metric manifolds. We investigate -Ricci solitons in the case when its potential vec…
Lightlike hypersurfaces of an -para Sasakian manifold
Selcen Yüksel Perktaş, Erol Kılıç, Mukut Mani Tripathi
In this paper, we initiate the study of lightlike hypersurfaces of an -almost paracontact metric manifold which are tangent to the structure vector field. In particular, we gi…
Einstein like -para Sasakian manifolds
Sadik Keleş, Erol Kiliç, Mukut Mani Tripathi +1
Einstein like -para Sasakian manifolds are introduced. For an -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in te…
Slant and Semi-Slant Submanifolds of a Lorentzian Almost Paracontact Manifold
Selcen Yüksel Perktaş, Erol Kiliç, Sadik Keleş
In this paper we define and study the slant and semi-slant submanifolds of a Lorentzian almost paracontact manifold. Some necessary and sufficient conditions for a submanifold of a…
On -para Sasakian 3-manifolds
Selcen Yüksel Perktaş, Erol Kılıç, Mukut Mani Tripathi +1
In this paper we study the 3-dimensional -para Sasakian manifolds. We obtain an necessary and sufficient condition for an -para Sasakian 3 -manifol…
Hypersurfaces of Lorentzian para-Sasakian manifolds
Selcen Yuksel Perktas, Erol Kilic, Sadik Keles
In this paper, we study the invariant and noninvariant hypersurfaces of (1,1,1) almost contact manifolds, Lorentzian almost paracontact manifolds and Lorentzian para-Sasakian manif…
Indefinite almost paracontact metric manifolds
Mukut Mani Tripathi, Erol Kilic, Selcen Yuksel Perktas +1
In this paper we introduce the concept of -almost paracontact manifolds, and in particular, of -para Sasakian manifolds. Several examples are presente…
