Stochastic evolution of cosmological parameters in the early universe

摘要

We develop a stochastic formulation of cosmology in the early universe, after consid- ering the scatter in the redshift-apparent magnitude diagram in the early epochs as an observational evidence for the non-deterministic evolution of early universe. We consider the stochastic evolution of density parameter in the early universe after the inflationary phase qualitatively, under the assump- tion of fluctuating w factor in the equation of state, in the Fokker-planck formalism.
