Jordan, Brans-Dicke theory.
Properties of the static, spherically symmetric solutions in the Jordan, Brans-Dicke theory. ABSTRACT. We have studied the properties of the static, spherically symmetric solution of Jordan, Brans-Dicke theory. An exact interior solution for standard space-time line element in the Schwarzschild form is obtained.
متن کاملBrans-Dicke theory: Jordan vs Einstein Frame
It is well known that, in contrast to general relativity, there are two conformally related frames, the Jordan frame and the Einstein frame, in which the Brans-Dicke theory, a prototype of generic scalar-tensor theory, can be formulated. There is a long standing debate on the physical equivalence of the formulations in these two different frames. It is shown here that gravitational deflection o...
متن کاملNucleosynthesis constraints on an extended Jordan-Brans-Dicke theory.
In a natural extension of the Jordan{Brans{Dicke theory the scalar eld can couple much more strongly to dark than to visible matter. New limits on the coupling constants of the model are obtained from standard big{bang nucleosynthesis.
متن کاملComposite spherically symmetric configurations in Jordan-Brans-Dicke theory
In this article, a study of the scalar field shells in relativistic spherically symmetric configurations has been performed. We construct the composite solution of Jordan-Brans-Dicke field equation by matching the conformal Brans solutions at each junction surfaces. This approach allows us to associate rigorously with all solutions as a single glued ”space”, which is a unique differentiable man...
متن کاملBrane World Cosmology In Jordan-Brans-Dicke Theory
We consider the embedding of 3+1 dimensional cosmology in 4+1 dimensional Jordan-BransDicke theory. We show that exponentially growing and power law scale factors are implied. Whereas the 4+1 dimensional scalar field is approximately constant for each, the effective 3+1 dimensional scalar field is constant for exponentially growing scale factor and time dependent for power law scale factor.
