Gauss–Bonnet models with cosmological constant and non zero spatial curvature in $$D=4$$ D=4
Abstract In the present paper the possibility of eternal universes in Gauss-Bonnet theories of gravity in four dimensions is analysed. It is shown that, for zero spatial curvature and zero cosmological constant, if the coupling is such that $$0<f'(\phi )\le c \exp (\frac{\sqrt{8}}{\sqrt{10}}...
