Abstract |
We review modified gravity models which provide the unification of inflation with dark energy era. Special attention is paid to F(R) gravity. Universality of gravitational alternative for accelerated expansion is indicated, as the corresponding unification maybe achived also in modified Gauss-Bonnet gravity, non-local gravity or modified gravity with extra scalars. The ocurrence of finite-time singularities at dark energy and/or inflation era is discussed. The possibility of bouncing cosmology from extended gravity is also shown. Finally, dark matter may naturally enter this scenario as third party of unification, for instance, in mimetic generalization of modified gravity. |
