Localization of nonlocal cosmological models with quadratic potentials
  in the case of double roots
  Nonlocal cosmological models with quadratic potentials are considered. We
study the action with an arbitrary analytic function F(\Box_g), which has both
double and simple roots. The formulae for nonlocal energy-momentum tensor,
which correspond to double roots, have been obtained. The way to find
particular solutions for nonlocal Einstein equations in the case when F(\Box_g)
has both simple and double roots has been proposed. One and the same functions
solve the initial nonlocal Einstein equations and the obtained local Einstein
equations.
