Nonlocal Modification of Newtonian Gravity
  The Newtonian regime of a recent nonlocal extension of general relativity
(GR) is investigated. Nonlocality is introduced via a scalar "constitutive"
kernel in a special case of the translational gauge theory of gravitation,
namely, the teleparallel equivalent of GR. In this theory, the nonlocal aspect
of gravity simulates dark matter. A nonlocal and nonlinear generalization of
Poisson's equation of Newtonian gravitation is presented. The implications of
nonlocality for the gravitational physics in the solar system are briefly
studied.
