Bianchi Type VI0 Cosmological Models with Perfect Fluid and Dark Energy

We consider a self-consistent system of Bianchi Type VI 0 cosmology and binary mixture of perfect fluid and dark energy. The perfect fluid is taken to be one obeying the usual equation of state p = γρ with γ ∈[0,1]. The dark energy is considered to be either the quintessence or Chaplygin gas. Exact...

Zusammenfassung:We consider a self-consistent system of Bianchi Type VI 0 cosmology and binary mixture of perfect fluid and dark energy. The perfect fluid is taken to be one obeying the usual equation of state p = γρ with γ ∈[0,1]. The dark energy is considered to be either the quintessence or Chaplygin gas. Exact solutions to the corresponding Einstein’s field equations are obtained as a quadrature. Models with power-law and exponential expansion have discussed in detail.
