Time-dependent cosmological constant in the Jackiw-Teitelboim cosmology

High Energy Physics - Theory 2010-12-17 v2

Abstract

We study the obtainment of a time-dependent cosmological constant at D=2 in a model based on the Jackiw-Teitelboim cosmology. We show that the cosmological term goes to zero asymptotically and can induce a nonsingular behavior at the origin.
