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…

A functional for Spin(7) forms
Calin Iuliu Lazaroiu, C. S. Shahbazi
We characterize the set of all conformal Spin(7) forms on an oriented and spin Riemannian eight-manifold as solutions to a homogeneous algebraic equation of degree two for…

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…
