چکیده

We study a general Scalar-Tensor Theory with an arbitrary coupling funtion !( ) but also an arbitrary dependence of the gravitational constant G( ) in the cases in which either one of them, or both, do not admit an analytical inverse, as in the hyperextended in ationary scenario. We present the full set of eld equations and study their cosmological behavior. We show that different scalar-tensor theories can be grouped in classes with the same solution for the scalar eld.

Slow Roll In ation in Non-Minimally Coupled Theories: Hyperextended Gravity Approach

The slow roll approximation is studied for cosmological models in Hyperextended Scalar-Tensor Theories of Gravity. A procedure to obtain slow roll solutions in non-minimally coupled gravity is outlined and some examples are provided. An integral condition over the functional form of the non-minimal coupling is imposed in order to obtain intermediate in ationary behavior. e-mail: dtorres@venus. ...

Light amplification by gravitational waves in scalar–tensor theories of gravity

It is shown that the amplification of a light beam by gravitational waves in scalar–tensor theories of gravity is a first order effect in the wave amplitudes. In general relativity, instead, the effect is only of second order. To appear in Astrophysical Letters and Communications Scalar–tensor theories (ST) of gravity have been considered as alternatives to general relativity (GR) for a long ti...

Singularities in scalar - tensor gravity

The analysis of certain singularities in scalar-tensor gravity contained in a recent paper is completed, and situations are pointed out in which these singularities cannot occur. Recently, Abramo et al. [1] have investigated certain geometric singularities occurring in the gravitational sector of scalar-tensor theories described by the action

Effective Gravitational “Constant” in Scalar-(Curvature)Tensor and Scalar-Torsion Gravities

In theories where a scalar field couples nonminimally to gravity, the effective gravitational “constant” becomes dependent on the value of the scalar field. This note first gives a brief review on how the cosmological evolution provides a dynamical stabilization for the gravitational “constant” as the system relaxes towards general relativity in matter dominated and potential dominated regimes ...
