A remark on operating groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
Let G be a finite group and H be an operator group of G. In this short note, we show a relationship between subnormal subgroup chains and H-invariant subgroup chains.

Some results on π-solvable and supersolvable groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
For a finite group G, ϕp(G), Sp(G), L(G) and S𝒫(G) are generalizations of the Frattini subgroup of G. We obtain some results on π-solvable, p-solvable and supersolvable groups with the help of the structures of these subgroups.

On supersolvability of fatorized finite groups [PDF]

open access: yesBulletin of Mathematical Sciences, 2013
Summary: We investigate the structure of finite groups that are products of two supersolvable groups and gain a sufficient condition for a group to be supersolvable. Our main theorem is the following: Let the group \(G=HK\) be the product of the subgroups \(H\) and \(K\).

Characterization of finite groups with a unique non-nilpotent proper subgroup [PDF]

open access: yesInternational Journal of Group Theory, 2021
‎We characterize finite non-nilpotent groups $G$ with a unique non-nilpotent proper subgroup‎. ‎We show that $|G|$ has at most three prime divisors‎. ‎When $G$ is supersolvable we find the presentation of $G$ and when $G$ is non-supersolvable we show ...

On c-Embedded Subgroups of Finite Groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2023
Let G be a group and H ≤ K ≤ G. We say that H is c-embedded in G with respect to K if there is a subgroup B of G such that G = HB and H ∩ B ≤ Z(K). Given a finite group G, a prime number p and a Sylow p-subgroup P of G, we investigate the structure of G ...

The structure of groups with cyclic commutator subgroups indecomposable to a subdirect product of groups [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
The article studies finite groups indecomposable to subdirect product of groups (subdirectly irreducible groups), commutator subgroups of which are cyclic subgroups.

A note on $1$-factorizability of quartic supersolvable Cayley graphs [PDF]

open access: yesTransactions on Combinatorics, 2018
Alspach et al‎. ‎conjectured that every quartic Cayley graph on an even solvable group is $1$-factorizable‎. ‎In this paper‎, ‎we verify this conjecture for quartic Cayley graphs on supersolvable groups of even order‎.

On non-normal cyclic subgroups of prime order or order 4 of finite groups

open access: yesOpen Mathematics, 2021
In this paper, we call a finite group GG an NLMNLM-group (NCMNCM-group, respectively) if every non-normal cyclic subgroup of prime order or order 4 (prime power order, respectively) in GG is contained in a non-normal maximal subgroup of GG.

Maximal Subgroup Containment in Direct Products [PDF]

open access: yesAdvances in Group Theory and Applications, 2016
Using the main theorem from [1] that characterizes containment of subgroups in a direct product, we provide a characterization of maximal subgroups contained in a direct product.
