Description
I will describe how the geometrical properties of the target manifold affect the inflationary predictions of two-field scalar-tensor theories invariant under dilatations. The results presented extend the predictions of the Higgs-dilaton model to a full class of theories defined by an underlying principle. In particular, I will show that when the field-derivative space in the Einstein frame is maximally symmetric during inflation, the inflationary predictions
are universal and independent of the details of the theory.
