On Nonlocal Modified Gravity and Cosmology

Abstract

Despite many nice properties and numerous achievements, general relativity is not a complete theory. One of actual approaches towards more complete theory of gravity is its nonlocal modification. We present here a brief review of nonlocal gravity with its cosmological solutions. In particular, we pay special attention to two nonlocal models and their nonsingular bounce solutions for the cosmic scale factor.Comment: 11 pages, Published in Springer Proceedings in Mathematics & Statistics 111 (2014) 251-26
