Einstein-Brans-Dicke Cosmology
We studied the Einstein-Brans-Dicke cosmology in detail. The difference of the evolution of the universe is significant between Einstein-Brans-Dicke cosmology and standard big-bang model during the radiation-dominated era. The power-law evolution of the scale factor is fast enough to solve the cosmological puzzles and slow enough to avoid the graceful exit problem. However, the constraints from...

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 Field Equations
We present the static spherically symmetric vacuum solutions of the Jordan, Brans-Dicke field equations. The new solutions are obtained by considering a polar Gaussian, isothermal and radial hyperbolic metrics.
متن کاملInflationary Brans-Dicke Quantum Universe
The formulation of Brans-Dicke (BD) gravity with matter in the Einstein frame is realized as Einstein gravity with dilaton and dilaton coupled matter. We calculate the one-loop 4d anomaly–induced effective action (EA) due to N dilaton coupled massless fermions on the time dependent conformally flat background with non-trivial dilaton. Using such (complete) effective action, the (fourth-order) q...
متن کاملString and Brans-Dicke Theories
We present the static, spherically symmetric solutions of the low energy d = 4 string. They form a simple generalisation of the Schwarzschild solution and describe the gravitational field of a spherical star in perturbative string theory. If the Robertson parameter γ is different from one, these solutions describe singular objects with naked singularities at their horizons, and whose Hawking te...
