Abstract
We apply the nested algebraic Bethe ansatz method to solve the eigenvalue p roblem for the SU(4) extension of the Hubbard model. The Hamiltonian is equ ivalent to the SU(4) graded permutation operator. The graded Yang-Baxter eq uation and the graded Quantum Inverse Scattering Method are used to obtain the eigenvalue of the SU(4) extension of the Hubbard model.
