Static Generalized Brans-Dicke Universe and Gravitational Waves Amplification
arXiv:gr-qc/0111099
Abstract
We find a static solution for the scale-factor in a Brans-Dicke generalized theory where the scalar field and the coupling constant vary with time. We find also that in the early Universe there may be amplification of gravitational waves.
