On the slow roll expansion of one-field cosmological models
Calin Iuliu Lazaroiu
We study the infrared scale expansion of single field cosmological models using the Hamilton-Jacobi formalism, showing that its specialization at unit scale parameter recovers the…
Dynamical consistency conditions for rapid turn inflation
Lilia Anguelova, Calin Iuliu Lazaroiu
We derive consistency conditions for sustained slow roll and rapid turn inflation in two-field cosmological models with oriented scalar field space, which imply that inflationary m…
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…
Dynamical renormalization and universality in classical multifield cosmological models
C. I. Lazaroiu
We study the scaling behavior of classical multifield cosmological models with complete scalar manifold and positive smooth scalar potential , introducing…
