On consistency conditions for strong SRRT inflation in two-field cosmological models
Elena-Mirela Babalic, Calin-Iuliu Lazaroiu
We discuss the strong version of the consistency conditions for SRRT inflation in general two-field cosmological models. In the fiducial case, this condition is a geometric PDE whi…
Strong rapid turn inflation and contact Hamilton-Jacobi equations
E. M. Babalic, C. I. Lazaroiu, V. O. Slupic
We consider the consistency condition for ``strong'' sustained rapid turn inflation with third order slow roll (SRRT) in two-field cosmological models with oriented scalar manifold…
Infrared behavior in tame hyperbolizable two-field models
Elena Mirela Babalic, Calin Iuliu Lazaroiu
We discuss the behavior of cosmological curves and their first order infrared approximants near critical ends of the scalar manifold and near interior critical points of the sc…
Noether Symmetries of Two-Field Cosmological Models
Lilia Anguelova, Elena Mirela Babalic, Calin Iuliu Lazaroiu
We summarize our work on "hidden" Noether symmetries of multifield cosmological models and the classification of those two-field cosmological models which admit such symmetries.
Hidden symmetries of two-field cosmological models
Lilia Anguelova, Elena Mirela Babalic, Calin Iuliu Lazaroiu
We determine the most general time-independent Noether symmetries of two-field cosmological models with rotationally-invariant scalar manifold metrics. In particular, we show that…
Cosmological flows on hyperbolic surfaces
Elena Mirela Babalic, Calin Iuliu Lazaroiu
We outline the geometric formulation of cosmological flows for FLRW models with scalar matter as well as certain aspects which arise in their study with methods originating from th…
