Viachaslau I. Murashka, Yana A. Kuptsova
We investigate the properties of the intersection of all -maximal subgroups of a finite group for a hereditary formation $\mathfr…
On the Length of a Maximal Subgroup of a Finite Group
Viachaslau I. Murashka, Alexander F. Vasil'ev
For a finite group and its maximal subgroup we proved that the generalized Fitting height of can't be less by 2 than the generalized Fitting height of and the non-$…
Formations of Finite Groups in Polynomial Time: the -Hypercenter
Viachaslau I. Murashka
For a wide family of formations (which includes Baer-local formations) it is proved that the -hypercenter of a permutation finite group can be compute…
Formations of Finite Groups in Polynomial Time: the -Radical
Viachaslau I. Murashka
For a Baer-local (composition) Fitting formation the polynomial time algorithm for the computation of the -radical of a permutation group is suggested.…
Constructing regular saturated formations of finite soluble groups
Viachaslau I. Murashka
For a formation of finite groups consider a graph whose vertices are elements of a finite group and two vertices are connected by an edge if and only if they generat…

Viachaslau I. Murashka
Let be subgroups of the permutation group of degree with and be a partition of the set of all different prime divisors of . We prove…
A test for a local formation of finite groups to be a formation of soluble groups with the Shemetkov property

The generalized Fitting height of a finite group is the least number such that , where , and $\mathrm{F}_{(i+1)…
Formations of Finite Groups in Polynomial Time: -residuals and -subnormality
Viachaslau I. Murashka
For a wide family of formations it is proved that the -residual of a permutation finite group can be computed in a polynomial time. Moreover, if in th…
On ECP-Groups

According to T. Foguel a subgroup of a group is called conjugate-permutable if for every . Mingyao Xu and Qinhai Zhang studied finite groups with every…
Fitting like subgroups of finite groups
Viachaslau I. Murashka, Alexander F. Vasil'ev
In this paper the concept of -functorial of a finite group was introduced. These functorials have many properties of the Fitting subgroup of a soluble group and the gen…
A generalization of Hall's theorem on hypercenter
Viachaslau I. Murashka, Alexander F. Vasil'ev
Let be a partition of the set of all primes and be a hereditary formation. We described all formations for which the -hypercenter a…
On a generalization of one Kramer's theorem
Viachaslau I. Murashka
Yangming Li and Xianhua Li in 2012 proposed a conjecture that generalizes O.U. Kramer's result about supersoluble groups. Here we proved that this conjecture is false in the genera…

Viachaslau I. Murashka, Alexander F. Vasil'ev
In this paper we study the groups all whose maximal or all Sylow subgroups are --subnormal in their product the with generalizations of the Fitting subgroup $\math…

Viachaslau I. Murashka
In this paper one construction of composition formations was introduced. This construction contains formations of quasinilpotent groups, -supersoluble groups, groups defined by…

On classes of finite groups with simple non-abelian chief factors
V. I. Murashka
Let be a class of non-abelian simple groups and be a class of groups. A chief factor of a group is called -central in prov…

Let and for all be a partition of the set of all primes into mutually disjoint subsets. In this paper we considered subgroups…
On generalizations of Baer's theorems about the hypercenter of a finite group
V. I. Murashka
We investigate the intersection of normalizers and -subnormalizers of different types of systems of subgroups (-maximal, Sylow, cyclic primary). We desc…

In this paper we introduced an arithmetic graph function which associates with every group G the directed graph whose vertices corresponds to the divisors of |G|. With the help of…
One formation of finite groups
Viachaslau I. Murashka
It is shown that two formations of finite groups, one was introduced by V.S. Monakhov and V.N. Kniahina and another one was introduced by R. Brandl, are coincides.
