Asymptotics of flat, radiation universes in quadratic gravity
Spiros Cotsakis, Antonios Tsokaros
We consider the asymptotics of flat, radiation-dominated isotropic universes in four-dimensional theories with quadratic curvature corrections which may arise when contributions re…

Flat, radiation universes with quadratic corrections and asymptotic analysis
Spiros Cotsakis, Antonios Tsokaros
It was shown long ago by T. V. Ruzmaikina and A. A. Ruzmaikin that within the framework of a homogeneous and isotropic cosmological model quadratic corrections of the gravitational…
