Convergence of Scalar-Tensor theories toward General Relativity and Primordial Nucleosynthesis
A. Serna, J. -M. Alimi, A. Navarro
In this paper, we analyze the conditions for convergence toward General Relativity of scalar-tensor gravity theories defined by an arbitrary coupling function (in the Einstein…
Asymptotic and Exact Solutions of Perfect-Fluid Scalar-Tensor Cosmologies
A. Navarro, A. Serna, J. -M. Alimi
We present a method which enables exact solutions to be found for at homogeneous and isotropic scalar-tensor cosmologies with an arbitrary function and satisfying the genera…
Stability of rotating spherical stellar systems
J. -M. Alimi, J. Perez, A. Serna
We study the stability of rotating collisionless self-gravitating spherical systems by using high resolution N-body experiments on a Connection Machine CM-5. We added rotation to O…
Constraints on the Scalar-Tensor theories of gravitation from Primordial Nucleosynthesis
Arturo Serna, Jean-Michel Alimi
We present a detailed calculation of the light element production in the framework of Scalar-Tensor (ST) theories of gravitation. The coupling function ωhas been described by an ap…
Scalar-Tensor Cosmological Models
Arturo Serna, Jean-Michel Alimi
We analyze the qualitative behaviors of scalar-tensor cosmologies with an arbitrary monotonic function. In particular, we are interested on scalar-tensor theories distinguis…
