Mixed doubly sequential warped product manifolds
Physica ScriptaAbstract This research aims to expand the understanding of solutions to Einstein’s field equations by introducing a new class of warped product manifolds, specifically mixed doubly sequential manifolds. The study delves into the geometry of these manifolds by analyzing critical metrics, including curvature tensors, covariant derivatives,

Geometric analysis of Riemannian doubly warped product submersions
Physica ScriptaAbstract This paper introduces the concept of Riemannian doubly warped product submersions as a natural generalization of Riemannian warped product submersions. We study some fundamental properties of such submersions and derived the conditions under which the Riemannian doubly warped product submersions have totally geodesic, totally ...

On doubly warped products as gradient Ricci-Yamabe solitons
Quaestiones MathematicaeWe characterize the gradient Ricci-Yamabe soliton of a doubly warped product manifold and provide a classification for (Figure presented.) We further establish the conditions for the doubly warped product manifold to be a gradient Ricci-Yamabe soliton and demonstrate this result for a physical model of the universe, namely, for the doubly warped ...
