Application of Mixed Generalized Quasi-Einstein Spacetimes in General Relativity

Abstract

In the present article, some geometric and physical properties of MG(QE)n were investigated. Moreover, general relativistic viscous fluid MG(QE)4 spacetimes with some physical applications were studied. Finally, through a non-trivial example of MG(QE)4 spacetime, we proved its existence.
