Abstract
We present a family of exact solutions to the Einstein field equations which describe inhomogeneous generalizations of spatially flat FRW co smologies. The self-interacting scalar field with an exponential poten tial of the form V approximately e(kphi) serves as a source for the ex pansion. We show that these inhomogeneous models never inflate and bri efly discuss the implications of our results on the genericity of infl ation and isotropization at late times.
