Slow rolling, inflation and quintessence

Abstract

We comment on the choice of the quintessence potential, examining the slow-roll approximation in a minimally coupled theory of gravity. We make some considerations on the potential behaviors, the related γparameter, and their relationships to phantom cosmology.
