用可解子群的阶的集合刻画散在单群
A Characterization of Spoadic Simple Groups by A Set of Orders of Their Solvable Subgroups
【摘要】 日本学者Seiichi Abe在2002年证明了有限单群A1(q),Sz(q),3D4(q),G2(q),2G2(q)可仅用可解子群的阶的集合进行刻画.本文证明了对所有散在单群可仅用可解子群的阶集合进行刻画.
【Abstract】 In this paper the author have proved the following theorem,which solves a problem of S.Abe and N.Iiyori for sporadic simple groups.Theorem:Let G be a finite group and S be one of sporadic simple groups,then GS if and only if Ord(S-(sol)(G))=Ord(S-(sol)(S)),where Ord(S-(sol)(G)) is the set of orders of solvable subgroups in G.
