GRADIENT $\rho$-EINSTEIN SOLITONS AND APPLICATIONS

open access: yes
In this paper, we mainly study gradient $\rho$-Einstein solitons on doubly warped product manifolds. More explicitly, we obtain necessary and sufficient conditions for a doubly warped product manifold to be a gradient $\rho$-Einstein soliton.
