Abstract
In this paper, we prove a sufficient condition for two long-range orde rs being either present or absent simultaneously in the absolute groun d state of a lattice many-body boson or fermion model. As an applicati on of this theorem, we give a simplified proof on the coexistence of t he resonating valence bond (RVB) long-range order and the on-site-pair ing long-range order in the ground state of the Hubbard model.
