Gravitational Waves in Generalised Brans-Dicke Theory
Abstract
We have solved cosmological gravitational Wave(GW)equation in the frame work of Generalised Brans-Dicke(GBD) theory for all epochs of the Universe.The solutions are expressed in terms of the present value of the Brans-Dicke coupling parameter ω(φ).It is seen that the solutions represent travelling growing modes for negative values of ω0 for all epochs of the Universe.
