Six-dimensional cosmological models with conformal extensions
Daniel Muller, Sergey G. Rubin, Ilya L. Shapiro +1
We consider the background cosmological solutions in the (six-dimensional) model with one time and five space coordinates. The theory of our interest has the action composed b…

Generalized Lemaître time for rotating and charged black holes and its near-horizon properties
A. V. Toporensky, O. B. Zaslavskii
We consider the behavior of the analogue of the Lemaitre time when a particle approaches the horizon of a rotating black hole. For the Kerr metric, the aforementioned time coincide…

Initial conditions for Starobinsky inflation in general quadratic gravity
Daniel Muller, Alexey Toporensky
We consider initial conditions leading to Starobinsky inflation in the general quadratic gravity, where the action of the theory contains one more curvature square invariant in add…
