Nonlocal action for long-distance modifications of gravity theory

Barvinsky, A O (Lebedev Physics Institute)

2003

Abstract: We construct the covariant nonlocal action for recently suggested long-distance modifications of gravity theory motivated by the cosmological constant and cosmological acceleration problems. This construction is based on the special nonlocal form of the Einstein-Hilbert action explicitly revealing the fact that this action within the covariant curvature expansion begins with curvature-squared terms.
