Natural coordinates and horizontal approximations in two-field cosmological models
Calin Iuliu Lazaroiu
We construct natural local coordinate systems on the phase space of two-field cosmological models with orientable target space, which allow for a description of cosmological flows…

Natural observables and dynamical approximations in multifield cosmological models
Calin Iuliu Lazaroiu
I give a geometric construction of certain first order natural dynamical observables in multifield cosmological models with arbitrary target space topology and discuss a system of…

The infrared behavior of tame two-field cosmological models
Elena Mirela Babalic, Calin Iuliu Lazaroiu
We study the first order infared behavior of tame hyperbolizable two-field cosmological models, defined as those classical two-field models whose scalar manifold is a connected, or…
