差分方程的对称性与可积性:Adler-Bobenko-Suris情形

Integrability and Symmetries of Difference Equations: the Adler-Bobenko-Suris Case

P. Xenitidis

摘要:

我们考虑Adler-Bobenko-Suris分类的偏差分方程,其特征在于多维一致。后一个性质自然地导致了这类方程的自B {}cklund变换和拉克斯对的构造。给出了它们的对称性分析,并明确地构造了广义对称的无限族。

英文摘要:

We consider the partial difference equations of the Adler-Bobenko-Suris classification, which are characterized as multidimensionally consistent. The latter property leads naturally to the construction of auto-B{ä}cklund transformations and Lax pairs for all the equations in this class. Their symmetry analysis is presented and infinite hierarchies of generalized symmetries are explicitly constructed.
