Gauss–Bonnet models with cosmological constant and non zero spatial curvature in D= 4

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≤cexp(810ϕ), then there are solutions that are eternal. Simila...
