【 摘 要 】

The general two-dimensional fermion system with repulsive interactions (typified by the Hubbard model) is bosonized, taking into account the finite on-shell forward-scattering phase shift derived in earlier papers. By taking this phase shift into account in the bosonic commutation relations, a consistent picture emerges showing the charge-spin separation and anomalous exponents of the Luttinger liquid.
