Ωζ-foliated Fitting Classes [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020
All groups under consideration are assumed to be finite. For a nonempty subclass of Ω of the class of all simple groups I and the partition ζ = {ζi | i ∈ I}, where ζi is a nonempty subclass of the class I, I = ∪i∈I ζi and ζi ∩ ζj = ø for all i ≠ j, ΩζR ...

A characterization of dominant local Fitting classes

open access: yesJournal of Algebra, 2012
A Fitting class \(\mathcal F\) is called dominant in the class \(\mathcal S\) of all finite soluble groups if \(\mathcal F\subseteq\mathcal S\) and for every group \(G\in\mathcal S\) any two \(\mathcal F\)-maximal subgroups of \(G\) containing the \(\mathcal F\)-radical \(G_{\mathcal F}\) are conjugated in \(G\).

Weakly totally permutable products and Fitting classes [PDF]

open access: yesInternational Journal of Group Theory, 2021
It is known that if $ G=AB $ is a product of its totally permutable subgroups $ A $ and $ B $‎, ‎then $ G\in \mathfrak{F} $ if and only if $ A\in \mathfrak{F} $ and $ B\in \mathfrak{F} $ when $ \mathfrak{F} $ is a Fischer class containing the class ...

Metanilpotent fitting classes [PDF]

open access: yesJournal of the Australian Mathematical Society, 1974
Hawkes showed in [10] that classes of metanilpotent groups which are both formations and Fitting classes are saturated and subgroup closed; more, he characterized all such classes as those local formations with a local definition consisting of saturated formations (of nilpotent groups).

Products of Finite Connected Subgroups

open access: yesMathematics, 2020
For a non-empty class of groups L, a finite group G=AB is said to be an L-connected product of the subgroups A and B if 〈a,b〉∈L for all a∈A and b∈B. In a previous paper, we prove that, for such a product, when L=S is the class of finite soluble groups ...

On a Special Weighted Version of the Odd Weibull-Generated Class of Distributions

open access: yesMathematical and Computational Applications, 2021
In recent advances in distribution theory, the Weibull distribution has often been used to generate new classes of univariate continuous distributions. They find many applications in important disciplines such as medicine, biology, engineering, economics,
