The Nagaoka instability and the existence of off-diagonal long-range order (ODLRO) and superconductivity for two holes near half-filling in 1d, 2d, and 3d hypercubes with periodic boundary conditions are exactly proven in the Hubbard model immersed in a strong magnetic field. The upper critical field and criteria for stability of either the spin-flipped or excitonic phases as a function of interaction strength are found. The theory predicts the possibility of the ODLRO mechanism of superconductivity in the strong-repulsion Hubbard model in arbitrary dimensions.
