Superconducting in the near half-filling hubbard-model

H. A. Tuan, N. T. Thang, N. N. Thuan

The Hubbard model of strongly correlated electron systems is considered near half-filling within the framework of a new functional integral method without slave bosons. A dynamical system of equations determining the superconducting phase of the Hubbard model is derived. Both singlet and triplet Cooper pairings are studied.
