Conformal Collineations and Ricci Inheritance Symmetry in String Cloud and String Fluids

Abstract

Conformal collineations (a generalization of conformal motion) and Ricci inheritance collineations, defined by ${\pounds }_{\xi }{R}_{ab}=2\alpha R_{ab}$, for string cloud and string fluids in general relativity are studied. By investigating the kinematical and dynamical properties of such fluids and using the field equations, some recent studies on the restrictions imposed by conformal collineations are extended, and new results are found.
