离散拉克斯对与可积差分系统族

Discrete Lax pairs and hierarchies of integrable difference systems

Pavlos Kassotakis

摘要:

我们介绍了一个家庭的顺序$N\in \mathbb{N}$拉克斯矩阵的索引由自然数$k\in \{1,\ldots,N-1\}.$为每个值的$k$,他们作为强拉克斯矩阵的层次的可积差分系统的边缘变量,反过来导致层次的可积差分系统的顶点变量或在边缘和顶点变量的组合。进一步地,将Lax矩阵的元素看作除环的元素,得到了在非交换域上扩展的离散可积系统的族.

英文摘要:

We introduce a family of order $N\in \mathbb{N}$ Lax matrices that is indexed by the natural number $k\in \{1,\ldots,N-1\}.$ For each value of $k$ they serve as strong Lax matrices of a hierarchy of integrable difference systems in edge variables that in turn lead to hierarchies of integrable difference systems in vertex variables or in a combination of edge and vertex variables. Furthermore, the entries of the Lax matrices are considered as elements of a division ring, so we obtain hierarchies of discrete integrable systems extended in the non-commutative domain.
