在局部有限群理论中的一个主要问题是,在有限群上的任何饱和融合系统是否允许相关的中心链接系统,以及当它允许时,它是否是唯一的。这两个问题的回答是肯定的Chermak,使用理论的部分群体和地方,他发展。利用切尔马克的思想结合阻塞理论的技巧,鲍勃奥利弗给出了切尔马克定理的不同证明。本文将奥利弗的证明推广到离散群上的融合系统,从而积极地解决了局部紧群理论中的类似问题.
A major question in the theory of-local finite groups was whether any saturated fusion system over a finite-group admits an associated centric linking system, and when it does, whether it is unique. Both questions were answered in the affirmative by Chermak, using the theory of partial groups and localities he developed. Using Chermak's ideas combined with the techniques of obstruction theory, Bob Oliver gave a different proof of Chermak's theorem. In this paper, we generalize Oliver's proof to the context of fusion systems over discrete-toral groups, thus positively resolving the analogous questions in-local compact group theory.
