The lull understanding· ol’the solution Гог the 1-tl Hubbard model is of interest in its own right, and may provide clues to the understanding of higher dimensioned systiMiis. We have found tin? exact solution of tlie model for tw<j eh'ctrons, with a magnetic flux ар[)Н(ч1, and showed some new results. We have also made calculations for more than two electrons on a looj) with a magnetic flux through it, using the Bethe-ansatz equations. Within the assumption that oxygen orbitals may play a fundarnentid role in the superconductive properties of Си —О high IT matc.'iials, exact calculaticnis ol the ground-stat<' eu<‘igy for two electrons in the contraction mechanism have been performed, do test the beginning assumption, some numerical calculations have been i)resent(;d.
