Abstract |
|
|
| The object of the present paper is to study mixed generalized quasi-Einstein manifolds by using the properties of the Z - tensor. Also we prove that mixed generalized quasi-Einstein GRW space-times admitting Z -tensor reduce to Einstein space-times or perfect fluid space-times provided φ=constant. Finally, a non-trivial example of MG(QE)4-space-times are given.
