摘要：

In this article, we characterize a spacetime endowed with Q-curvature tensor. We acquire that a Q-flat perfect fluid spacetime is either, vacuum or, a de-Sitter spacetime. Moreover, it is established that a Q-flat perfect fluid spacetime becomes a Robertson-Walker spacetime. Besides, it is proved that a Q-recurrent spacetime is a generalized Ricci recurrent spacetime. Finally, we examine the impact of Q-flat perfect fluid spacetime solutions in f R, T, RijTij)-gravity.
