Open Inflation With Scalar-tensor Gravity
The open inflation model recently proposed by Hawking and Turok is investigated in scalar-tensor gravity context. If the dilaton-like field has no potential, the instanton of our model is singular but has a finite action. The GibbonsHawking surface term vanishes and hence, can not be used to make Ω0 nonzero. To obtain a successful open inflation one should introduce other matter fields or a pot...
متن کاملOpen Inflation With The Scalar-tensor Gravity
The open inflation model recently proposed by Hawking and Turok is investigated in the scalar-tensor gravity context. If the dilaton-like field has no potential, the instanton of our model is singular but has a finite action. The Gibbons-Hawking surface term vanishes and hence, can not be used to make Ω be nonzero. Introducing four-form fields, we can obtain the desired Ω value with fine tuning...
متن کاملConstraints from inflation on scalar-tensor gravity theories.
We show how observations of the perturbation spectra produced during inflation may be used to constrain the parameters of general scalar-tensor theories of gravity, which include both an inflaton and dilaton field. An interesting feature of these models is the possibility that the curvature perturbations on super-horizon scales may not be constant due to non-adiabatic perturbations of the two f...
متن کاملHyperextended scalar-tensor gravity.
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...
متن کامل1/R gravity and Scalar-Tensor Gravity
We point out that extended gravity theories, the Lagrangian of which is an arbitrary function of scalar curvature R, are equivalent to a class of the scalar tensor theories of gravity. The corresponding gravity theory is ω = 0 BransDicke gravity with a potential for the Brans-Dicke scalar field, which is not compatible with solar system experiments if the field is very light: the case when such...
