群代数中的动力扭

Dynamical twists in group algebras

Pavel Etingof, Dmitri Nikshych

摘要:

对有限群的群代数中的动力扭进行了分类。也就是说,我们建立了一个双射对应规范等价类的动力学扭曲(这是一个特定的非线性泛函方程的解决方案)和同构类的“动力学数据”描述的纯群论术语。这推广了Movshev和Etingof-Gelaki所得到的通常扭曲的分类。

英文摘要:

We classify dynamical twists in group algebras of finite groups. Namely, we set up a bijective correspondence between gauge equivalence classes of dynamical twists (which are solutions of a certain non-linear functional equation) and isomorphism classes of ``dynamical data'' described in purely group theoretical terms. This generalizes the classification of usual twists obtained by Movshev and Etingof-Gelaki.
