Query: A New Iterative Perturbation Scheme for Lattice Models with Arbitrary
  Filling   We derive a new perturbation scheme for treating the large d limit of lattice
models at arbitrary filling. The results are compared with exact
diagonalization data for the Hubbard model and found to be in good agreement.
