The solution of the dark energy problem in models without scalars is presented. It is shown that a late-time accelerating cosmology may be generated by an ideal fluid with some implicit equation of state. The evolution of the universe within modified Gauss–Bonnet gravity is considered. It is demonstrated that such a gravitational approach may predict the (quintessential, cosmological constant or transient phantom) acceleration of the late-time universe with a natural transition from deceleration to acceleration (or from non-phantom to phantom era in the last case).

Modified Gravity and Cosmology (2011, background): “The cosmologies of these theories, and theories with inverse powers of αĜ+βR added to the Einstein-Hilbert action (where α and β are constants), have been considered in [391, 979], while the FLRW solutions of other R+f(Ĝ) theories have been considered in [971, 323].”
