Intricacies of cosmological bounce in polynomial metric<i>f</i>(<i>R</i>) gravity for flat FLRW spacetime
In this paper we present the techniques for computing cosmological bounces in polynomial f(R) theories, whose order is more than two, for spatially flat FLRW spacetime. In these cases the conformally connected Einstein frame shows up multiple scalar potentials predicting various possibilities of cosmological evolution in the Jordan frame where …
