作为丛代数的Q-系

Q-systems as cluster algebras

Rinat Kedem

摘要:

Q系统最早出现在XXX模型和广义海森堡自旋链的贝特方程的分析中。已知任何简单李代数和许多其他Kac-Moody代数都存在这样的系统。用簇代数的语言构造了与任意单、单缀李代数g相联系的Q-系,并讨论了$Q$ -系的解在初始变量下的多项式性质与簇代数中的Laurent现象之间的关系.

英文摘要:

Q-systems first appeared in the analysis of the Bethe equations for the XXX-model and generalized Heisenberg spin chains. Such systems are known to exist for any simple Lie algebra and many other Kac-Moody algebras. We formulate the Q-system associated with any simple, simply-laced Lie algebras g in the language of cluster algebras, and discuss the relation of the polynomiality property of the solutions of the $Q$-system in the initial variables, which follows from the representation-theoretical interpretation, to the Laurent phenomenon in cluster algebras.
