Abstract

Abstract : Smooth double crossing of the phantom divide linew Λ = − 1 has been found possible with a single minimally coupled scalar field for the most simple form of generalized k -essence cosmological model, in the presence of background cold dark matter. Such crossing is a sufficiently late time transient phenomenon and does not have any pathological behaviour.
