Title: Accelerated Universe and Modified Gravity

Abstract: There are alternative models of dark energy to the cosmological scenario. One of such models is modified gravity which produce a long range force. If this fifth force is welcomed at large scales, we need to find some mechanism to suppress it locally for the consistency with local gravity constraints. I will present two mechanisms which produce this effect: the chameleon and Vainshtein mechanisms.
