Nonlocal de Sitter gravity and its exact cosmological solutions

Abstract This paper is devoted to a simple nonlocal de Sitter gravity model and its exact vacuum cosmological solutions. In the Einstein-Hilbert action with Λ term, we introduce nonlocality by the following way: R − 2 Λ = R − 2 Λ R − 2 Λ → R − 2 Λ F □ R − 2 Λ $$ R-2\Lambda =\sqrt{R-2\Lambda}\kern1em...
