Using the energy function on the extended Siegel-Jacobi upper half space of order , , with , the equations of motion in the variables $…
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…
Connection matrices on the Siegel-Jacobi upper half space and extended Siegel-Jacobi upper half space
Elena Mirela Babalic, Stefan Berceanu
The inverse of the metric matrices on the Siegel-Jacobi upper half space , invariant to the restricted real Jacobi group and extended Siege…
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…
