• ACCELERATING AND DECELERATING COSMOLOGICAL MODELS WITH PERFECT FLUID AND DARK ENERGY FOR KASNER TYPE METRIC
Abstract
We consider a self-consistent system of Kasner Universe cosmology and binary mixture of perfect fluid and dark energy. The perfect fluid is taken to be one obeying the usual equation of state with γ [0, 1]. The dark energy is considered to be either the quintessence or Chaplygin gas. Exact solutions to the corresponding Einstein equations are obtained as a quadrature. Models with power-law and exponential expansion have discussed in detail.
Keywords
Cosmological models• Perfect fluid • Dark energy • Cosmological parameters.
