Abstract

In this work, perfect fluid spacetimes obeying Gray's decompositions have been studied. In the first part, after a brief summary about Gray's decompositions used in this study, we work on properties of perfect fluid spacetimes obeying these decompositions. The results are obtained for different subspaces of a perfect fluid spacetime. Thereafter, we present the characterizations of these spacetimes by proving some theorems.
