Abstract
A simple algebraic approach to exact solutions of the hard-core Fermi-Hubba rd model is proposed. Excitation energies and the corresponding wavefunctio ns of the hard-core Fermi-Hubbard model with nearest neighbor hopping cases in high dimension are obtained by using this method, which manifests that the model is exactly solvable in any dimension.
