Some general results in self-creation cosmologies

Abstract

Raychaudhuri-type equations are written for a cosmological model filled with perfect fluid and obeying the equations of a self-creation theory recently proposed by G.A. Barber. In addition some general results on spatially homogenous cosmological models are obtained. The Hawking-Penrose energy condition suggest that the singularity can be avoided in this theory. © 1985.
