Abstract

A non-local modified gravity model with an analytic function of the d’Alembert operator that has been proposed as a possible way of resolving the singularities problems in cosmology is considered. We show that the anzats that is usually used to obtain exact solutions in this model provides a connection with f ( R ) gravity models.
