Abstract: (IOP)
The authors consider some anisotropic model universes filled with a homogeneous self-interacting scalar field with exponential potential (V approximately ealpha phi ). Specifically, by assuming power law behaviour for the scale factors they are able to find exact solutions of Einstein equations for homogeneous Bianchi III and VI cosmologies. They compare the behaviour of these models with that of flat and open FRW solutions with similar scalar fields and show that neither of the obtained anisotropic solutions inflate.- astrophysics: anisotropy
