Characterizations of generalized Robertson-Walker spacetimes concerning gradient solitons

K De, MNI Khan, UC De - Heliyon, 2024 - cell.com
In this article, we examine gradient type Ricci solitons and\(m, τ\)-quasi Einstein solitons in
generalized Robertson-Walker (GRW) spacetimes. Besides, we demonstrate that in this …

-quasi-Einstein solitons on -dimensional trans-Sasakian manifolds and its applications in spacetimes

A Sarkar, U Biswas - International Journal of Geometric Methods in …, 2023 - World Scientific
This paper characterizes (m, ρ)-quasi-Einstein solitons on 3-dimensional trans-Sasakian
manifolds. It has been shown that a closed (m, ρ)-quasi-Einstein soliton on a 3-dimensional …
