Geometric and physical characteristics of mixed super quasi-Einstein manifolds.

The authors consider a mixed super quasi-Einstein manifold, which is conducive to understanding deeply the global characteristics of the universe including its topology. Firstly, the existence of such manifolds is ensured by an interesting example. Then, the authors determine the curvature characterizations of a class of mixed super quasi-Einstein manifolds. Finally, the present paper depicts a W 2 -conservative characteristic of mixed super quasi-Einstein manifolds associated with a recurrent generator. [ABSTRACT FROM AUTHOR]
