摘要：

The energy spectrum of the one-dimensional Hubbard model with U=∞ is derived using the Bethe ansatz. The ground state energy is degenerated and it is equal to the energy of free spinless fermions with periodic or antiperiodic boundary conditions. The ground state energies calculated using the different mean-field theories are compared with the exact result. © 1990.
