The hidden symmetries of multifield cosmological models and Hesse geometry
I give a characterization of multifield cosmological modelswhich admit Hidden Noether symmetries through the existence of nontrivial solutions to a certain Hessian equation defined by theirscalar field metric and describe the geometric properties of theirscalar manifolds. As an application, I classify all two fieldmodels which admit such symmetries using uniformization theory.
