Exact results for the Hubbard model on bipartite lattices in spatial dimensions $d > 1$ : Seven theorems from the full [SU(2) $\times$ SU(2) $\times$ U(1)]/ $Z_{2}^{2}$ symmetry

J. M. P. Carmelo

There are few exact results for the Hubbard model on bipartite lattices of spatial dimension $d > 1$ . Nevertheless, the Hubbard model with transfer integral $t$ and onsite repulsion…
