      abstract     = {There exists presently considerable debate over the
                      question whether local Coulomb interactions can explain the
                      absence of the small e'(g) Fermi surface hole pockets in
                      photoemission studies of Na0.3CoO2. By comparing dynamical
                      mean field results for different single particle
                      Hamiltonians and exact diagonalization as well as quantum
                      Monte Carlo treatments, we show that, for realistic values
                      of the Coulomb energy U and Hund exchange J, the e'(g)
                      pockets can be slightly enhanced or reduced compared to band
                      structure predictions, but they do not disappear.},
