    "abstract": "We find a solution for exponential inflation in Brans-Dicke cosmology endowed\nwith a cosmological term, which includes time-varying shear and vorticity. We\nfind that the scalar field and the scale factor increase exponentialy while\nshear, vorticity, energy density, cosmic pressure and the cosmological term\ndecay exponentialy for beta \u003c 0, where beta is defined in the text.",
