Abstract:
Let I be the class of all finite simple groups and f:I→{Fitting classes of groups}. The Fitting class F=KR(f)=(G:OA,A′(G)∈f(A) for any A∈K(G)) is referred to as a canonical Fitting class with satellite f. A non-singly-generated totally canonical Fitting class F is said to be critical non-singly-generated if all proper totally canonical Fitting subclasses in F are singly generated. In the paper, a complete description of the structure of the critical non-singly-generated totally canonical Fitting classes of finite groups is obtained.
Keywords:
finite simple group, Fitting class, Fitting formation, satellite, singly generated Fitting class, local formation of finite groups.
