Hypersurface-Homogenous Cosmological Models with Perfect Fluid & Dark Energy

Abstract

We consider a self-consistent system of Hypersurface Homogenous cosmology and Binary Mixture of perfect fluid and dark energy. The perfect fluid is taken to be obeying equations of state p = γρ with γ ∈ [0, 1]. The dark energy is considered to be obeying a quintessence or Chaplygin gas. Exact solutions to the corresponding Einstein’s field equations are obtained as a quadrature. Furthermore power law models and exponential models are investigated.
