Kaluza-Klein Type Dissipative Future Universe without Big Rip

Abstract

Kaluza-Klein type dissipative future universe without big rip in the context of Ecart formalism has been investigated. In this model, the generalized Chaplygin gas is considered as a model for dark energy characterized by equation of state p=-A/(ρ^1/α). We have found that in Kaluza-Klein type universe, when the cosmic dark energy behaves simultaneously like a fluid with equation of state p=ωρ; ω<-1 as well as Chaplygin gas, big rip problem does not arise and the scale factor is found to be regular for all time.
