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…
