Infrared behavior in tame hyperbolizable two-field models

Abstract

We discuss the behavior of cosmological curves and their first order infrared approximants near critical ends of the scalar manifold $\Sigma$ and near interior critical points of the scalar potential for tame hyperbolizable two-field cosmological models by determining the universal forms of the asymptotic gradient flow of the classical effective potential with respect to the uniformizing metric near all these points and ends. We compare the asymptotic behavior of gradient flow curves with numerical results for cosmological curves.
