Scalar-tensor -cosmologies
arXiv:gr-qc/0011086
Abstract
We show that the scalar-tensor -model action is conformally equivalent to general relativity with a minimally coupled wavemap with a particular target metric. Inflation on the source manifold is then shown to occur in a natural way due both to the arbitrary curvature couplings and the wavemap self-interactions.
