q-潘勒韦方程保联络变形的格结构Ⅰ

The Lattice Structure of Connection Preserving Deformations for q-Painlevé Equations I

Christopher M. Ormerod

摘要:

我们希望探索$q$ -潘勒韦方程的Lax可积性和$q$ -潘勒韦方程的对称性之间的联系。我们将证明,引起$q$ -潘勒韦方程的连接保持变形可以被认为是其相关线性问题的施莱辛格变换群的元素。这些群具有非常自然的晶格结构。每一个Schlesinger变换都导出了$q$ -潘勒韦方程的一个贝克隆变换。每个平移贝克隆变换可以提升到相关线性问题的水平,有效地表明每个平移贝克隆变换允许一个拉克斯对。我们将为$q$ -潘勒韦方程(包括$q$ - $\mathrm{P}_{\mathrm{VI}}$)演示此框架。

英文摘要:

We wish to explore a link between the Lax integrability of the $q$-Painlevé equations and the symmetries of the $q$-Painlevé equations. We shall demonstrate that the connection preserving deformations that give rise to the $q$-Painlevé equations may be thought of as elements of the groups of Schlesinger transformations of their associated linear problems. These groups admit a very natural lattice structure. Each Schlesinger transformation induces a Bäcklund transformation of the $q$-Painlevé equation. Each translational Bäcklund transformation may be lifted to the level of the associated linear problem, effectively showing that each translational Bäcklund transformation admits a Lax pair. We will demonstrate this framework for the $q$-Painlevé equations up to and including $q$-$\mathrm{P}_{\mathrm{VI}}$.
