On the dual theory of a result of Bryce and Cossey

Autor: Baojun Li, Nanying Yang, N. T. Vorob’ev

Publikováno v: Journal of Algebra. 522:124-133

In the theory of formations of finite soluble groups, a well known result of Bryce and Cossey is: a local formation F is a Fitting class if and only if every value of the canonical formation function F of F is a Fitting class. In this paper, we give

On Injectors of a Hartley Set of a Finite Group

Autor: Nanying Yang, T. B. Vasilevich, N. T. Vorob'ev

Publikováno v: Algebra Colloquium. 25:671-680

Let G be a finite group and [Formula: see text] be a Hartley set of G. In this paper, we prove the existence and conjugacy of [Formula: see text]-injectors of G and describe the characterization of injectors via radicals. As applications, some known

On ℱ-injectors of fitting set of a finite group

Autor: Wenbin Guo, Nanying Yang, N. T. Vorob’ev

Publikováno v: Communications in Algebra. 46:217-229

Let G be some generalized π-soluble groups and ℱ be a Fitting set of G. In this paper, we prove the existence and conjugacy of ℱ-injectors of G and give a description of the structure of the injectors.

On σ-local Fitting classes

Autor: N. T. Vorob’ev, Li Zhang, Wenbin Guo

Let σ be a partition of the set of all primes P . If G is a finite group and F is a Fitting class of finite groups, the symbol σ ( G ) denotes the set { σ i | σ i ∩ π ( | G | ) ≠ ∅ } and σ ( F ) = ∪ σ ∈ F σ ( G ) . We call any funct

Finite π-groups with normal injectors

Autor: A. V. Martsinkevich, N. T. Vorob’ev

Publikováno v: Siberian Mathematical Journal. 56:624-630

Denote by P the set of all primes and take a nonempty set π ⊆ P. A Fitting class F = (1) is called normal in the class Sπ of all finite soluble π-groups or π-normal, whenever F ⊆ Sπ and for every G ∈ Sπ its F-injectors constitute a normal
