Quintessence duality

High Energy Physics - Theory 2008-11-26 v2

Abstract

We join quintessence cosmological scenarios with the duality simmetry existing in string dilaton cosmologies. Actually, we consider the tracker potential type V=V0/ϕαV = V_0/{\phi}^{\alpha} and show that duality is only established if α=2\alpha = - 2.
