| Abstract: | Field equations in the presence of a perfect fluid distribution are obtained in a scalar-tensor theory of gravitation proposed
by Saez and Ballester (Phys. Lett. 113, 1985, 467) with the aid of Einstein–Rosen cylindrically symmetric metric. A static vacuum model and a non-static stiff fluid
model are presented. The physical and geometrical properties of the stiff fluid model are studied. |
