Abstract

We employ the generalized Chaplygin gas of interacting dark energy to obtain the equation of state for the generalized Chaplygin gas energy density in a non-flat universe. By choosing a negative value for B we see that w_Λ ^eff<-1, which corresponds to a universe dominated by phantom dark energy.
