Asymptotic Freedom from Induced Gravity Cosmology
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 Geff → 0 for t → −∞ and, for some of them, Geff → GN for t → ∞, where GN is the Newton constant.

متن کاملMultiple field scalar-tensor theories of gravity and cosmology.
We consider multiple scalar elds coupled to gravity, with special attention given to twoeld theories. First, the conditions necessary for these theories to meet solar system tests are given. Next, we investigate the cosmological evolution of the elds to see if these conditions can be met. Solutions are found in the dust era, as well as radiation and cosmological constant dominated epochs. The p...
متن کاملTensor-vector-scalar-modified gravity: from small scale to cosmology.
The impressive success of the standard cosmological model has suggested to many that its ingredients are all that one needs to explain galaxies and their systems. I summarize a number of known problems with this programme. They might signal the failure of standard gravity theory on galaxy scales. The requisite hints as to the alternative gravity theory may lie with the modified Newtonian dynami...
متن کاملAsymptotic Freedom Cosmology
For a general class of scalar–tensor gravity theories, we discuss how to recover asymptotic freedom regimes when cosmic time t → ±∞. Such a feature means that the effective gravitational coupling Geff → 0, while cosmological solutions can asymptotically assume de Sitter or power–law behaviours. In our opinion, through this mechanism, it is possible to cure some shortcomings in inflationary and ...
متن کاملInteractions in Scalar Field Cosmology
We investigate spatially flat isotropic cosmological models which contain a scalar field with an exponential potential and a perfect fluid with a linear equation of state. We include an interaction term, through which the energy of the scalar field is transferred to the matter fields, consistent with a term that arises from scalar–tensor theory under a conformal transformation and field redefin...
