摘要：

In this paper we study a model of modified gravity with non-minimal coupling between a general function of the Gauss-Bonnet invariant, f(G), and matter Lagrangian from the point of view of the energy conditions. Such model has been introduced in Nojiri et al. (Phys. Lett. B 651: 224, 2007) for description of early inflation and late-time cosmic acceleration. We present the suitable energy conditions for the above mentioned model and then, we use the estimated values of the Hubble, deceleration and jerk parameters to apply the obtained energy conditions to the specific class of modified Gauss-Bonnet models.
