On Almost C(α)-Manifold Satisfying Certain Curvature Conditions
This research article is about the geometry of the almost C(α)- manifold. Some important properties of the almost C(α)- manifold with respect to the W_3- curvature tensor, such as W_3-flat and W_3- semi-symmetry, are investigated.

Study of η-einstein soliton on α-sasakian manifold admitting schouten-van kampen connection [PDF]
The purpose of the present paper is to study some properties of α -Sasakian manifolds with respect to Schouten-van Kampen connection. We study η-Einstein soliton on pseudo-projectively flat α-Sasakian manifolds with respect to Schouten-van Kampen ...

Sequential Warped Products: Curvature and Killing Vector Fields
In this note, we introduce a new type of warped products called as sequential warped products to cover a wider variety of exact solutions to Einstein's equation. First, we study the geometry of sequential warped products and obtain covariant derivatives,

Some solitons on anti-invariant submanifold of LP-Kenmotsu manifold admitting Zamkovoy connection [PDF]
In this paper we prove some curvature properties of anti-invariant submanifold of Lorentzian para-Kenmotsu manifold (briefly, LP-Kenmotsu manifolds) with respect to Zamkovoy connection (∇∗).

IDEAL characterization of isometry classes of FLRW and inflationary spacetimes
In general relativity, an IDEAL (Intrinsic, Deductive, Explicit, ALgorithmic) characterization of a reference spacetime metric $g_0$ consists of a set of tensorial equations $T[g]=0$, constructed covariantly out of the metric $g$, its Riemann curvature ...

The primary objective of the article is to investigate the symmetry and pseudosymmetry properties of the Reissner-Nordström-de Sitter (briefly, RNdS) spacetime. The secondary aim of the paper is to explore the notion of Ricci solitons in RNdS spacetimes.

On the conharmonic and concircular curvature tensors of almost C($\lambda $) Manifolds
The object of the present paper is to characterize certain curvature conditions on conharmonic and concircular curvature tensors on almost C($\lambda $) manifolds. In this paper we study conharmonically flat, $\xi $-conharmonically flat, concircularly flat and $\xi $-concircularly flat almost C($\lambda $) manifolds.
