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