Abstract

We study a general field theory of a scalar field coupled to gravitation through a quadratic Gauss-Bonnet term ξ(ϕ)\xi({\phi})RGB2R_{GB}^2. We show that, under mild assumptions about the function ξ(ϕ)\xi(\phi), the classical solutions in a spatially flat FRW background include singularity - free solutions.
