The effect of curvature in thawing models
Abstract
We study the evolution of spatial curvature for thawing class of dark energy models. We examine the evolution of the equation of state parameter, wφ, as a function of the scale factor a, for the case in which the scalar field φ evolve in nearly flat scalar potential. We show that all such models provide the corresponding approximate analytical expressions for wφ(φ,k) and wφ(a). We present observational constraints on these models.
