Inflation in inhomogeneous cosmology

Physical Review D, 1992
We discuss the onset of inflation in an inhomogeneous, asymptotically Friedmann-Robertson-Walker universe coupled to a scalar inflaton field. We consider a three-parameter family of inhomogeneous Cauchy data, for which we can solve analytically the constraint equations.

Cosmological perturbations from inflation

Journal of Physics A: Mathematical and Theoretical, 2007
Matter is distributed very homogeneously and isotropically on scales larger than a few hundred Mpc. The measurements of the microwave background temperature fluctuations show that at recombination the universe was extremely homogeneous and isotropic (with accuracy ∼10 −4 ) on all scales up to the present horizon (Spergel et al 2006 Preprint astro-ph ...

Homogeneous Cosmological Models and New Inflation

Physical Review Letters, 1986
The promise of the inflationary-universe scenario is to free the present state of the universe from extreme dependence upon initial data. Paradoxically, inflation is usually analyzed in the context of the homogeneous and isotropic Robertson-Walker cosmological models.
