非均匀格上超几何型差分方程的因式分解:动力代数

Factorization of the hypergeometric-type difference equation on the non-uniform lattices: dynamical algebra

R. Álvarez-Nodarse, N. M. Atakishiyev, R. S. Costas-Santos

摘要:

证明了在一般情况下,超几何型差分方程可以在非均匀格上因式分解。它表明,在大多数情况下的q-线性谱的特征值,这直接导致动力学对称代数$su_q(1,1)$,其生成元显式构造的差分算子,在因式分解的过程中获得。因此,所有具有$q$线性谱的模型(它们中的一些,但不是全部,以前在许多出版物中考虑过)可以以统一的形式处理。

英文摘要:

We argue that one can factorize the difference equation of hypergeometric type on the nonuniform lattices in general case. It is shown that in the most cases of q-linear spectrum of the eigenvalues this directly leads to the dynamical symmetry algebra $su_q(1,1)$, whose generators are explicitly constructed in terms of the difference operators, obtained in the process of factorization. Thus all models with the $q$-linear spectrum (some of them, but not all, previously considered in a number of publications) can be treated in a unified form.
