我们证明了适当的舒尔多项式的q-类似物提供了第n个KdV层次的q-变形的合理解。这允许我们构造q差算子的双谱交换环的显式例子。
We show that appropriate q-analogues of the Schur polynomials provide rational solutions of a q-deformation of the Nth KdV hierarchy. This allows us to construct explicit examples of bispectral commutative rings of q-difference operators.
