Reconstruction Procedure for Nonlocal Gauss-Bonnet Models

20 Sep 2019  ·  Elizalde Emilio, Pozdeeva Ekaterina O., Vernov Sergey Yu. ·

We investigate the cosmological dynamics of nonlocally corrected gravity involving a function of the inverse d'Alembertian acting on the Gauss-Bonnet term. Casting the dynamical equations in local form, we derive the reconstruction procedure. We find conditions on the model parameters that are sufficient for the existence of de Sitter solutions and obtain these solutions explicitly.
