We compare some features of quintessence cosmological scenarios with the duality symmetry existing in string dilaton cosmologies. Actually, we consider the tracker potential with V(phi) inversely proportional to the alpha power of phi and show that duality is only established if alpha = −2.

Abstract

We compare some features of quintessence cosmological scenarios with the duality symmetry existing in string dilaton cosmologies. Actually, we consider the tracker potential with V(phi) inversely proportional to the alpha power of phi and show that duality is only established if alpha = −2.
