| 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 negative beta, where beta is defined in the text. |
