(部分)斜正交多项式的Christoffel变换及其应用

Christoffel transformations for (partial-)skew-orthogonal polynomials and applications

Shi-Hao Li, Guo-Fu Yu

摘要:

本文研究了斜正交多项式和部分斜正交多项式的Christoffel变换。我们证明了Christoffel变换可以作为离散可积族的谱问题,因此我们从这些变换中得到某些可积族。一些约化的情况也被考虑。

英文摘要:

In this article, we consider the Christoffel transformations for skew-orthogonal polynomials and partial-skew-orthogonal polynomials. We demonstrate that the Christoffel transformations can act as spectral problems for discrete integrable hierarchies, and therefore we derive certain integrable hierarchies from these transformations. Some reductional cases are also considered.
