摘要：
We use scaled variables to display a set coupled equations valid for isotropic and anisotropic Bianchi type I, V, IX models in scalar-tensor theories, including Dehnen's induced gravity theory. In particular, for the Brans-Dicke theory the equations decouple and one is able to integrate the system for FRW and Bianchi I and V models. Additionally, we analyze the possibility that anisotropic models asymptotically isotropize, and/or possess inflationary properties.
