The object of the present paper is to study the properties of N (k)-quasi Einstein manifolds.
The existence of some classes of such manifolds are proved by constructing physical and …

In the present paper we have studied the curvature tensors of a normal paracontact metric
manifold satisfying the conditions R(ξ,Y)W^*=0, W^*(ξ,Y)R=0, W^*(ξ,Y)Z=0, W^*(ξ,Y)S=0 and …

We set a definition of a (0, 2)-type tensor on the generalized Sasakian-space-forms. The
necessary and sufficient conditions for W-semisymmetric generalized Sasakian-space forms …

In the present paper, we aim to study Yamabe soliton and Riemann soliton on Lorentzian
para-Sasakian manifold. First, we proved, if the scalar curvature of an 𝜂-Einstein Lorentzian …

In the context of para-contact Hausdorff geometry η-Ricci solitons and gradient Ricci solitons
are considered on manifolds. We establish that on an (LCS) n-manifold (M, ϕ, ξ, η, 𝑔), the …

In this paper, we consider an η-Ricci soliton on the (LCS) n-manifolds (M, φ, ξ, η, g)
satisfying certain curvature conditions likes: R (ξ, X)· S= 0 and W2 (ξ, X)· S= 0. We show that …

The present study initially identify the generalized symmetric connections of type
$(\alpha,\beta) $, which can be regarded as more generalized forms of quarter and semi …
