A note on splitting solutions in dimensional quadratic gravity
Daniel Müller, Alexey Toporensky
In the present paper we consider anisotropic cosmological vacuum solutions in (4+1) dimensional general quadratic gravity. In particular, we present a solution with 3 equal and 1 d…

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…
