提出了二维户田格点方程的q -差分形式。通过适当的约化,它可约化为圆柱形户田格点方程的q -差分形式.证明了约化方程存在用q -Bessel函数表示的解.
A q -difference version of the two-dimensional Toda lattice equation is proposed. Through a suitable reduction, it reduces to the q -difference version of the cylindrical Toda lattice equation. It is shown that the reduced equation admits solutions expressed by the q -Bessel function.
