| dc.description.abstract |
Despite its theoretical beauty and many phenomenological evidences,
general relativity is not a complete theory and should be modi ed. Namely, under
rather general conditions, general relativity yields cosmological solutions with zero
size of the universe at its beginning, what means an in nite matter density. In
order to solve this problem we consider nonlocal modi cation of general relativity.
In particular, we analyze two nonlocal models and present their nonsingular bounce
cosmological solutions for the cosmic scale factor. |
