| 英文摘要 | In this article, we consider the generalised two-parameter Cauchy two-matrix model and the corresponding integrable lattice equation. It is shown that with parameters chosen as 1/k(i), k(i) is an element of Z(>0) (i = 1, 2), the average characteristic polynomials admit (k(1)+ k(2)+ 2)-term recurrence relations, which can be interpreted as spectral problems for integrable lattices. The tau function is then given by the partition function of the generalised Cauchy two-matrix model as well as Gram determinant. The simplest solvable example is given. |
