An analysis of symmetry groups of generalized -quasi-Einstein manifolds
Volume 173 / 2023
Abstract
In this paper, emphasis is placed on how the behavior of the solutions of a system of PDEs is affected by the geometry of generalized m-quasi-Einstein manifold, and vice versa. Considering an n-dimensional generalized m-quasi-Einstein manifold which is conformal to a pseudo-Euclidean space, we find the most general symmetry group of maximal dimension. Moreover, we demonstrate that there is no other low-dimensional invariant on a generalized m-quasi-Einstein manifold. As an application, we use the invariant structure of the metric to provide an example of a shrinking m-quasi-Einstein manifold.
