Collineations of the Ricci tensor

Authors: Bokhari, Ashfaque H.; Qadir, Asghar;

Collineations of the Ricci tensor

Abstract

Ricci collineations for the Ricci tensor which is constructed from a general spherically symmetric and static metric are classified for all possibilities of Rab(r) (such that Rab≠0 for a=b). It turns out that the only collineations admitted by this tensor can be ten, six, or four and there does not appear any case in between.
