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, wø, as a function of the scale factor a, for the case in which the scalar field ø evolve in nearly flat scalar potential. We show that all such models provide the corresponding approximate analytical expressions for wøøk) and wø(a). We present observational constraints on these models.
