突变周期箭图、可积映射及相关Poisson代数
Mutation-Periodic Quivers, Integrable Maps and Associated Poisson Algebras
摘要:
我们考虑一类地图,最近在集群突变的背景下得出的。在本文中,我们开始与一个简短的审查的背景下,但随后转移到一个相关的泊松括号的讨论,随着泊松代数的一个特殊的家庭的功能与这些地图。一个双哈密顿结构的推导和使用构造一个序列的泊松交换功能,因此显示完全可积性。正则坐标的推导,与地图现在是一个典型的转换与一系列的交换不变的功能。兼容性的一对这些功能引起刘维方程和地图发挥作用的贝克隆变换。
英文摘要:
We consider a class of map, recently derived in the context of cluster mutation. In this paper we start with a brief review of the quiver context, but then move onto a discussion of a related Poisson bracket, along with the Poisson algebra of a special family of functions associated with these maps. A bi-Hamiltonian structure is derived and used to construct a sequence of Poisson commuting functions and hence show complete integrability. Canonical coordinates are derived, with the map now being a canonical transformation with a sequence of commuting invariant functions. Compatibility of a pair of these functions gives rise to Liouville's equation and the map plays the role of a Bäcklund transformation.
