Isotropization of Bianchi type models and a new FRW solution in Brans-Dicke theory

Abstract

Using scaled variables we are able to integrate an equation valid for isotropic and anisotropic Bianchi type I, V, IX models in Brans-Dicke (BD) theory. We analyze known and new solutions for these models in relation with the possibility that anisotropic models asymptotically isotropize, and/or possess inflationary properties. In particular, a new solution of curve ($k\ne 0$) Friedmann-Robertson-Walker (FRW) cosmologies in Brans-Dicke theory is analyzed.
