Symmetries of Toda type 3D lattices

I. T. Habibullin, A. R. Khakimova

AI总结:

该研究探讨Davey-Stewartson型耦合系统与二维Toda型格点的对偶性,描述新可积格点的对称性层级并给出显式对称形式,提出基于修饰链Darboux可积约化构造精确解的方法,还给出Volterra格点相关耦合系统的新解示例。

摘要:

本文讨论了一类Davey-Stewartson型耦合系统与一类二维Toda型格点之间的对偶关系。针对近期发现的可积格点,描述了其对称性层级,并以显式形式给出了二阶和三阶对称性,同时给出了对应的耦合系统。本文提出了一种基于修饰链的Darboux可积约化来构造耦合系统精确解的原创方法,并以与Volterra格点相关的耦合系统的若干新解作为说明性示例。

英文摘要:

The duality between a class of the Davey-Stewartson type coupled systems and a class of two-dimensional Toda type lattices is discussed. For the recently found integrable lattice the hierarchy of symmetries is described. Second and third order symmetries are presented in explicit form. Corresponding coupled systems are given. An original method for constructing exact solutions to coupled systems is suggested based on the Darboux integrable reductions of the dressing chains. Some new solutions for coupled systems related to the Volterra lattice are presented as illustrative examples.
