We introduce the concept of (ε)‐almost paracontact manifolds, and in particular, of (ε)‐para‐
Sasakian manifolds. Several examples are presented. Some typical identities for curvature …

In this article, we investigate anti-invariant Riemannian and Lagrangian submersions onto
Riemannian manifolds from the Lorentzian para-Sasakian manifold. We demonstrate that …

The object of the present paper is to study the invariant submanifolds of (LCS) n-manifolds.
We study semiparallel and 2-semiparallel invariant submanifolds of (LCS) n-manifolds …

In this paper we give necessary and sufficient conditions for spacelike and timelike curves in
a conformally flat, quasi conformally flat and conformally symmetric 4-dimensional …

The object of the present paper is to study some geometric conditions for an invariant
submanifold of an LP-Sasakian manifold to be totally geodesic. Further we consider …

We consider semiparallel and 2-semiparallel invariant submanifolds of Lorentzian para-
Sasakian manifolds. We show that these submanifolds are totally geodesic. We also …

The object of the present paper is to study the pseudoparallel, Ricci generalized
pseudoparallel and η-parallel invariant submanifolds of (LCS) n-manifolds and we obtained …

We study of warped product submanifolds, especially warped product hemi‐slant
submanifolds of LP‐Sasakian manifolds. We obtain the results on the nonexistance or …
