有界划分上的椭圆型Ruijsenaars差分算子

Elliptic Ruijsenaars difference operators on bounded partitions

Jan Felipe van Diejen, Tamás Görbe

摘要:

通过对参数的截断条件,将椭圆型Ruijsenaars差分算子限制在由有界划分编码的有限点格上.利用联合谱上的多项式构造了相应的联合本征函数的正交基。在三角极限,这恢复了对角化的截断麦克唐纳差分算子的麦克唐纳多项式的有限维基础。

英文摘要:

By means of a truncation condition on the parameters, the elliptic Ruijsenaars difference operators are restricted onto a finite lattice of points encoded by bounded partitions. A corresponding orthogonal basis of joint eigenfunctions is constructed in terms of polynomials on the joint spectrum. In the trigonometric limit, this recovers the diagonalization of the truncated Macdonald difference operators by a finite-dimensional basis of Macdonald polynomials.
