Shear and Vorticity in Inflationary Brans-Dicke Cosmology with Lambda-Term
Marcelo Samuel Berman
Abstract
We find a solution for exponential inflation in Brans-Dicke cosmology endowed with a cosmological term, which includes time-varying shear and vorticity. We find that the scalar field and the scale factor increase exponentialy while shear, vorticity, energy density, cosmic pressure and the cosmological term decay exponentialy for beta < 0, where beta is defined in the text.
