On cosmic acceleration in four-dimensional Einstein–Gauss–Bonnet gravity

“…More generally, in [54], the constraint is investigated in the context of the observed inequality, and it is concluded that the GB term has no direct or indirect (for some particular potential and coupling functions) role at the late time expansion. In [55], the problem was studied in the framework of a mass-varying dark matter, and it was shown that although the GB term has no direct impact on the late time acceleration, it may alleviate the coincidence problem. The problem for inflation and the primordial gravitational wave was discussed in [56,57].…”
