Extended matter bounce scenario in ghost free f(R,G) gravity compatible with GW170817
In the context of a ghost free f(R,G) model, an extended matter bounce scenario is studied where the form of the scale factor is given by a(t)=(a0t2+1)n. The ghost free character of the model is ensured by the presence of a Lagrange multiplier, as developed in [1]. The conditions under which, in thi...
