MATTER COLLINEATIONS OF BIANCHI V SPACETIME

Abstract

Matter collineations of the Bianchi V spacetime are studied according to degenerate or non-degenerate energy–momentum tensor. We have found that in degenerate case there are infinitely many matter collineations, whereas two cases give finite number of matter collineations which are five and six. When the energy–momentum tensor is non-degenerate, we obtain either four, five, six or seven independent matter collineations, out of which three are minimal Killing vectors and the rest are proper matter collineations.
