Quintessence duality

arXiv:hep-th/9907207 · doi:10.1142/S0218271801001438

Abstract

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