The sum rule for the moments of the spectral density is discussed for the single-band Hubbard model. It is shown that respecting the sum rule up to the order m 3 is conceptually important for a qualitatively correct description of the quasi-particle band structure in the strong-correlation regime. D
The Adler-Weisberger and Goldberger-Miyazawa-Oehme sum rules are calculated within a relativistic, unitary and crossing symmetric dynamical model for pion-nucleon scattering using two different methods: (1) by evaluating the scattering amplitude at the corresponding low-energy kinematics and (2) by
A quark model of hadrons is proposed, based on the collinear group SG(3) X SC(3) X ... X SU(3)(2j $ 1 cofactors). Relations are found within the framework of this model for the partial widths of meson and baryon resonances, as well as relations for the t,otal and differential cross-sections of :I rn
