On subgroups of ZJ type of an F-injector for Fitting classes F between E and ES.

Ana Martínez Pastor (1994)

Publicacions Matemàtiques

Similarity:

Let G be a finite group and p a prime. We consider an F-injector K of G, being F a Fitting class between E y ES, and we study the structure and normality in G of the subgroups ZJ(K) and ZJ*(K), provided that G verifies certain conditions, extending some results of G.

On complemented subgroups of finite groups

Long Miao (2006)

Czechoslovak Mathematical Journal

Similarity:

A subgroup H of a group G is said to be complemented in G if there exists a subgroup K of G such that G = H K and H ∩ K = 1 . In this paper we determine the structure of finite groups with some complemented primary subgroups, and obtain some new results about p -nilpotent groups.

Finite groups with an automorphism of prime order whose fixed points are in the Frattini of a nilpotent subgroup

Similarity:

In this paper it is proved that a finite group G with an automorphism α of prime order r, such that C G ⁢ α = 1 is contained in a nilpotent subgroup H, with H , r = 1 , is nilpotent provided that either H is odd or, if H is even, then r is not a Fermât prime.

On a class of finite solvable groups

James Beidleman, Hermann Heineken, Jack Schmidt (2013)

Open Mathematics

Similarity:

A finite solvable group G is called an X-group if the subnormal subgroups of G permute with all the system normalizers of G. It is our purpose here to determine some of the properties of X-groups. Subgroups and quotient groups of X-groups are X-groups. Let M and N be normal subgroups of a group G of relatively prime order. If G/M and G/N are X-groups, then G is also an X-group. Let the nilpotent residual L of G be abelian. Then G is an X-group if and only if G acts by conjugation on...
