“…Dark energy models motivated by holography have been the subject of a considerable amount of literature (e.g., 75,76]). As a special case, a generalized (but still second order) Gauss-Bonnet gravity discussed in [75] and applied to inflation in [76] produces modified Friedmann equations not too dissimilar from those appearing in this section.…”

We propose a new entropy construct that generalizes the Tsallis, Rényi, Sharma-Mittal, Barrow, Kaniadakis, and loop quantum gravity entropies and reduces to the Bekenstein-Hawking entropy in a certain limit. This proposal is applied to the Schwarzschild black hole and to spatially homogeneous and isotropic cosmology, where it is shown that it can potentially describe inflation and/or holographic dark energy.
