We calculate the one-hole spectral function for the polarized t-J model using exact diagonalization for a finite size cluster. A well-defined quasiparticle peak appears at the bottom of the spectrum for intermediate values of J. The momentum of the quasiparticle corresponding to the bottom of the ba

Long-range (r ~ p ~-~ >> lattice spacing) spin-wave exchange produces a very strong pairing of the holes. Solutions of the BCStype equation for the superconducting gap A are found for various symmetries. The strongest pairing corresponds to d wave symmetry. The physical reasons for the strong pairin
