Bianchi type-I model with cosmological constant in a generalized scalar-tensor theory of gravitation.

Bianchi type-I cosmological models are discussed in the Bergmann-Wagoner-Nordtvedt scalar-tensor theory where both the so-called cosmological constant ..lambda.. and the coupling parameter ..omega.. are taken to be functions of the scalar field phi. Exact solutions are obtained in Dicke's revised units assuming a very simple relationship between ..lambda.. and phi. The properties of the models are discussed in special cases.
