摘要：
Conformal Ricci collineations of static spherically symmetric spacetimes are studied.The general form ofthe vector fields generating conformal Ricci collineations is found when the Ricci tensor is non-degenerate,in which casethe number of independent conformal Ricci collineations is 15,the maximum number for four-dimensional manifolds.In the degenerate case it is found that the static spherically symmetric spacetimes always have an infinite number ofconformal Ricci collineations.Some examples are provided which admit non-trivial conformal Ricci collineations,andperfect fluid source of the matter.
