关于动力学杨-巴克斯特方程

On the dynamical Yang-Baxter equation

Pavel Etingof

摘要:

本次演讲的灵感来自于之前的两次ICM演讲,分别是V.Drinfeld(1986)和G.Felder(1994)。也就是说,德林费尔德的讲话的主要思想之一是,量子杨-巴克斯特方程(QYBE),这是一个重要的方程出现在量子场论和统计力学,是最好的理解范围内的霍普夫代数,或量子群。另一方面,在费尔德的演讲中,他解释说,另一个重要的数学物理方程,星三角关系,可以(而且应该)被视为QYBE的推广,其中解取决于额外的“动态”参数。文中还解释了量子动力学杨-巴克斯特方程的解可以与一种量子群相联系。这些想法产生了一个充满活力的新分支"量子代数“,它可以被称为动态量子群理论。我这次演讲的目的是对这一理论及其应用的某些方面作一个鸟瞰式的回顾。

英文摘要:

This talk is inspired by two previous ICM talks, by V.Drinfeld (1986) and G.Felder (1994). Namely, one of the main ideas of Drinfeld's talk is that the quantum Yang-Baxter equation (QYBE), which is an important equation arising in quantum field theory and statistical mechanics, is best understood within the framework of Hopf algebras, or quantum groups. On the other hand, in Felder's talk, it is explained that another important equation of mathematical physics, the star-triangle relation, may (and should) be viewed as a generalization of QYBE, in which solutions depend on additional ``dynamical'' parameters. It is also explained there that to a solution of the quantum dynamical Yang-Baxter equation one may associate a kind of quantum group. These ideas gave rise to a vibrant new branch of ``quantum algebra'', which may be called the theory of dynamical quantum groups. My goal in this talk is to give a bird's eye review of some aspects of this theory and its applications.
