Six-Dimensional Bianchi Type–I Universe with Wet Dark Fluid in General Relativity

Abstract

The six dimensional Bianchi Type-I Universe filled with dark energy from a wet fluid has been considered. A new equation of state for the dark energy component of the universe has been used. It is modeled on the equation of state p=γ(ρ-ρ_*) that can describe a liquid such as water. The exact solutions for constant deceleration parameter have been studied in detail for power–law and exponential forms both. The cases γ=1 and γ=0 have also been analyzed.
