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…
Consistency Condition for Slow-roll and Rapid-turn Inflation
Lilia Anguelova, Calin Iuliu Lazaroiu
We summarize our work on a consistency condition for inflation in two-field cosmological models, in the regime of rapid turn and third-order slow roll. To ensure a sustained inflat…
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…
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…
