论文摘要
我们研究了一个Abelian缺陷组和一个环状惯性商的块,自由行动,但不是传统的。我们证明,当p = 2时,这样的块是惯性的,即基本的莫里塔等于其brauer通讯员。加上第二作者对同射体缺陷组上的歌手周期动作的结果,这完成了2个块的分类,并以循环惯性商自由作用于Abelian缺陷组。
We study blocks with an abelian defect group and a cyclic inertial quotient acting freely but not transitively. We prove that when p=2, such blocks are inertial, i.e. basic Morita equivalent to their Brauer correspondent. Together with a result of the second author on Singer cycle actions on homocyclic defect groups, this completes the classification of 2-blocks with a cyclic inertial quotient acting freely on an abelian defect group.
