Abstract: Since the integrals of motion of the integrable one-dimensional Hubbard model cannot be understood in terms of the quantum inverse scattering method, a one-dimensional truncated Hubbard model is introduced. Unlike the ordinary model, the Hamiltonian of the truncated Hubbard model is Hermitian only in the continuum limit and has a number of methodical advantages. It can be diagonalized in case of an arbitrary number of components both for fermion and boson operators using the quantum inverse scattering method and the integrals of motion of this model are calculated in the course of the solution.
