有限群中Abel Sylow子群的识别

Recognising Abelian Sylow Subgroups in Finite Groups

Julian Brough

摘要:

设p为素数。证明了:如果有限群G具有非交换的Sylow p-子群,且G中每个p-元的类大小与p互质,则G包含一个具有相同性质的单群作为子商.此外,我们提供了一个列表中的所有单群和素数,使西洛p-子群是非阿贝尔和所有p-元素类大小互质的p.这提供了一个解决方案的问题,这是左后留下的Tiep和纳瓦罗建立,即p不等于3或5,那么这永远不会发生[NT 14]。

英文摘要:

Let p be a prime. We prove that if a finite group G has non-abelian Sylow p-subgroups, and the class size of every p-element in G is coprime to p; then G contains a simple group as a subquotient which exhibits the same property. In addition we provide a list of all the simple groups and primes such that the Sylow p-subgroups are non-abelian and all p-elements have class size coprime to p. This provides a solution to the problem which was left remaining after Tiep and Navarro established that is p is not equal to 3 or 5, then this can never happen [NT14].
