Five Dimensional Bianchi Type VI0 Dark Energy Cosmological Model in General Relativity

In this paper, we have constructed a self-consistent system of Bianchi Type VI0 cosmology in five dimensions with a binary mixture of perfect fluid and dark energy. The perfect fluid chosen here obeys the usual equation of state p = rho gamma with 0 <= gamma <= 1. The dark energy chosen is considered to be either the quintessence or Chaplygin gas. Exact solutions to the corresponding Einstein's field equations are obtained as a quadrature. The equation of state parameter for dark energy w is found to be consistent with the recent observations of SNe Ia data (SNe Ia data with CMBR anisotropy) and galaxy clustering statistics. Here, our models predict that the rate of expansion of universe would increase with passage of time. The physical and geometric aspects of the models are also discussed in detail.
