Groups without non abelian supersoluble subgroups are studied.
Groups without non abelian supersoluble subgroups are studied.
This Note concerns some questions about S-partitions of a finite group.
We prove that every abelian finite group is contained in the intersection of the nontrivial normal classes introduced by Zappa.
Groups all whose nonidentity subgroups split over a normal inseparable nonidentity subgroup are studied.
It is shown that for every finite abelian group B, there exists a finite soluble group G, such that , where is the minimal normal Fitting class.
We prove that every abelian finite group is contained in the intersection of the nontrivial normal classes introduced by Zappa.
Groups all whose nonidentity subgroups split over a normal inseparable nonidentity subgroup are studied.
We extend some results on Fitting classes of finite soluble groups to certain classes of infinite groups.
This Note is a summary of some results concerning inseparable finite groups.
Let be the property of soluble finite groups defined by if and only if every -subgroup of G is permutable with a fixed Hall -subgroup of G. Minimal non- groups are studied.
We give some sufficient conditions for the splitting of certain extensions of a finite -group by a group whose Sylow subgroups are elementary abelian.
This paper concerns some questions about S-partitions of finite soluble groups, and solves a problem proposed by G. Zappa in a recent Mathematical Symposium.
We study a finite translation structure with nontrivial dilatations and give a characterization of its translation group.
