设为有限群,令。在1896年,Frobenius证明了表示为交换子的方法的个数是,其中是Frobenius特征和。这个和在是(非阿贝尔)有限单群的情况下受到特别的关注,并提出了一些相关的证明。在本文中,我们讨论这些论点,反驳其中之一,并提供部分证据,有利于另一个。
Letbe a finite group and let. In 1896, Frobenius showed that the number of ways to expressas a commutator of elements ofis, whereis the Frobenius character sum.This sum received particular attention in the case whereis a (non‐abelian) finite simple group, and some related conjectures were posed. In this paper we discuss these conjectures, refute one of them, and provide partial evidence in favor of another one.
