摘要：
Examples of scalar conserved currents are presented for trigonometric, hyperbolic and elliptic versions of the Hubbard model with non-nearest neighbour variable range hopping. They support for the first time the hypothesis about the integrability of the elliptic version. The two-electron wave functions are constructed in an explicit form. (C) 2001 Elsevier Science B.V.
