Bianchi Type-I, v and VIo models in modified generalized scalar-tensor theory

Abstract

In modified generalized scalar-tensor (GST) theory, the cosmological term A is a function of the scalar field ø and its derivatives ø2. We obtain exact solutions of the field equations in Bianchi Type-I, V and VIo space-times. The evolution of the scale factor, the scalar field and the cosmological term has been discussed. The Bianchi Type-I model has been discussed in detail. Further, Bianchi Type-V and VIo models can be studied on the lines similar to Bianchi Type-I model. © Indian Academy of Sciences.
