摘要：

We present the exact ground-state wave function and energy of a general Hubbard model with kinetic energy t and on-site, nearest-neighbor, and bond-charge interaction U,V,X, respectively, for a wide, physically relevant range of parameters with X = t on lattices with arbitrary coordination numbers Z at half filling.
