Asymptotic freedom from induced gravity cosmology

General Relativity and Quantum Cosmology 2007-05-23 v1

Abstract

We give conditions to obtain cosmological asymptotic freedom in scalar-tensor theories of gravity. We show that this feature can be achieved in FRW flat spacetimes since we obtain singularity free solutions where the effective gravitational constant Geff0G_{eff}\rightarrow 0 for tt\rightarrow -\infty and, for some of them, GeffGNG_{eff}\rightarrow G_{N} for tt\rightarrow\infty, where GNG_{N} is the Newton constant.
