Nonlocal gravitational models and exact solutions

A nonlocal gravity model with a function f (□ −1 R ), where □ is the d’Alembert operator, is considered. The algorithm, allowing to reconstruct f (□ −1 R ), corresponding to the given Hubble parameter and the state parameter of the matter, is proposed. Using this algorithm, we find the functions f (...

Description
Summary:A nonlocal gravity model with a function f (□ −1 R ), where □ is the d’Alembert operator, is considered. The algorithm, allowing to reconstruct f (□ −1 R ), corresponding to the given Hubble parameter and the state parameter of the matter, is proposed. Using this algorithm, we find the functions f (□ −1 R ), corresponding to de Sitter solutions.
