Characterizations of generalized Robertson-Walker spacetimes concerning gradient solitons

Krishnendu De, Mohammad Nazrul Islam Khan, Uday Chand De

In this article, we examine gradient type Ricci solitons and $(m, τ)$ -quasi Einstein solitons in generalized Robertson-Walker ( $GR W$ ) spacetimes. Besides, we demonstrate that in thi…

Almost co-Kähler manifolds and $(m, ρ)$ -quasi-Einstein solitons

Krishnendu De, Mohammad Nazrul Islam Khan, Uday Chand De

The present paper aims to investigate $(m, ρ)$ -quasi-Einstein metrices on almost co-Kähler manifolds $M$ . It is proven that if a $(κ, μ)$ -almost co-Kähler manifold with $κ<…
