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.Research announcement, 2 pages, submitted for publication in the MG9 ProceedingsGeneral Relativity and Quantum CosmologyScalar-tensor $σ$-cosmologiestext
