    • Abstract


      In modified generalized scalar–tensor (GST) theory, the cosmological term 𝛬 is a function of the scalar field 𝜙 and its derivatives $\dot{\phi}^{2}$. 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.
