Abstract

In this work a new non-minimally coupled model is presented, where a generic function f(R)f(R) of the scalar curvature factors the usual Einstein-Hilbert action functional, motivated by relevant results obtained from similar models. Its cosmological dynamics are derived and the possibility of attaining a phase of accelerated expansion is assessed. To further probe the possible implications of the model, a dynamical system formulation is established, and used to assess the scenarios where f(R)f(R) assumes a power-law or exponential form.
