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…
Two-field Cosmological -attractors with Noether Symmetry
Lilia Anguelova, Elena Mirela Babalic, Calin Iuliu Lazaroiu
We study Noether symmetries in two-field cosmological -attractors, investigating the case when the scalar manifold is an elementary hyperbolic surface. This encompasses and gene…
Two-field cosmological models and the uniformization theorem
Elena Mirela Babalic, Calin Iuliu Lazaroiu
We propose a class of two-field cosmological models derived from gravity coupled to non-linear sigma models whose target space is a non-compact and geometrically-finite hyperbolic…
