Non-local gravity with a Weyl-square term
Recent work has shown that modifications of General Relativity based on the addition of a non-local term $R\,\Box^{-2}R$ produce a dynamical model of dark energy, which is cosmologically viable both at the background level and at the level of cosmological perturbations. We explore a more general cla...
