以1为根的动力学量子群

Dynamical quantum groups at roots of 1

Pavel Etingof, Dmitri Nikshych

摘要:

给出了有限维Hopf代数的动力学扭曲,利用Xu和Etingof-Varchenko的方法构造了两个弱霍普夫代数,并证明了它们是对偶的.我们将动力学量子群理论推广到量子参数q是单位单位根的情形。这些对象原来是自对偶的--这是一个全新的性质,通常的德林费尔德-吉姆博量子群不满足。

英文摘要:

Given a dynamical twist for a finite dimensional Hopf algebra we construct two weak Hopf algebras, using methods of Xu and Etingof-Varchenko, and show that they are dual to each other. We generalize the theory of dynamical quantum groups to the case when the quantum parameter q is a root of unity. These objects turn out to be self-dual -- which is a fundamentally new property, not satisfied by the usual Drinfeld-Jimbo quantum groups.
