Inflation in a universe with viscosity
Abstract
An exact spatially inhomogeneous solution of Einstein's equations is obtained where the energy stress tensor is that due to a viscous fluid and the false vacuum. The solution undergoes an exponential expansion with homogenization/isotropization, and the 3space section becomes flat in the timescale 1/sq rt(Lambda/3) as in the case of homogeneous models studied by Wald (1983).
