Non-Solvable Equation Systems with Graphs Embedded in Rn [PDF]

open access: yes, 2013
Different from the homogenous systems, a Smarandache system is a contra- dictory system in which an axiom behaves in at least two different ways within the same system, i.e., validated and invalided, or only invalided but in multiple distinct ...

A Class of Solvable Groups [PDF]

open access: yesCanadian Journal of Mathematics, 1959
Numerous studies have been made of groups, especially of finite groups, G which have a representation in the form AB, where A and B are subgroups of G. The form of these results is to determine various grouptheoretic properties of G, for example, solvability, from other group-theoretic properties of the subgroups A and B.More recently the structure of ...

Finite BCI-groups are solvable [PDF]

open access: yesInternational Journal of Group Theory, 2016
‎Let $S$ be a subset of a finite group $G$‎. ‎The bi-Cayley graph ${rm BCay}(G,S)$ of $G$ with respect to $S$ is an undirected graph with vertex set $Gtimes{1,2}$ and edge set ${{(x,1),(sx,2)}mid xin G‎, ‎ sin S}$‎. ‎A bi-Cayley graph ${rm BCay}(G,S)$ is

Refined solvable presentations for polycyclic groups [PDF]

open access: yesInternational Journal of Group Theory, 2012
We describe a new type of presentation that, when consistent, describes a polycyclic group. This presentation is obtained by re ning a series of normal subgroups with abelian sections.

GRUPOS DE PERMUTAÇÕES E GRUPOS FINITOS SIMPLES

open access: yesColloquium Exactarum, 2011
The normality of subgroups in a finite group has a property discovered by E. Galois in 1832, study-group of permutations of roots of polynomial equations.

On homogeneous spaces with finite anti-solvable stabilizers

open access: yesComptes Rendus. Mathématique, 2022
We say that a group is anti-solvable if all of its composition factors are non-abelian. We consider a particular family of anti-solvable finite groups containing the simple alternating groups for $n\ne 6$ and all 26 sporadic simple groups. We prove that,

Isomorphism versus commensurability for a class of finitely presented groups

open access: yes, 2014
We construct a class of finitely presented groups where the isomorphism problem is solvable but the commensurability problem is unsolvable. Conversely, we construct a class of finitely presented groups within which the commensurability problem is ...

Torsion-free covers of solvable minimax groups [PDF]

open access: yes, 2015
We prove that every finitely generated solvable minimax group can be realized as a quotient of a torsion-free solvable minimax group. This result has an application to the investigation of random walks on finitely generated solvable minimax groups.

Finite Almost Simple Groups whose Holomorph Contains a Solvable Regular Subgroup [PDF]

open access: yesAdvances in Group Theory and Applications
In our previous paper, we gave a complete list of the finite non-abelian simple groups whose holomorph contains a solvable regular subgroup. In this paper, we refine our previous work by considering all finite almost simple groups.
