Extraspecially Irreducible Groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2016
Given distinct prime numbers $q$ and $r$, we construct a semidirect product $CR$ with $R\vartriangleleft CR$, where $C$ is a cyclic group of order $q$, and $R$ is an extraspecial $r$-group, such that $C$ centralizes $R'$, and $R$ is minimal among the ...

A new approach to character-free proof for Frobenius theorem [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2023
Let G be a Frobenius group. Using character theory, it is proved that the Frobenius kernel of G is a normal subgroup of G, which is well-known as a Frobenius theorem. There is no known character-free proof for Frobenius theorem. In this note, we prove it,

Algorithmically finite groups

open access: yesJournal of Pure and Applied Algebra, 2011
We call a group $G$ {\it algorithmically finite} if no algorithm can produce an infinite set of pairwise distinct elements of $G$. We construct examples of recursively presented infinite algorithmically finite groups and study their properties. For instance, we show that the Equality Problem is decidable in our groups only on strongly (exponentially ...

FINITELY ANNIHILATED GROUPS [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2014
AbstractIn 1976, Wiegold asked if every finitely generated perfect group has weight 1. We introduce a new property of groups,finitely annihilated, and show that this might be a possible approach to resolving Wiegold’s problem. For finitely generated groups, we show that in several classes (finite, solvable, free), being finitely annihilated is ...

Finite Groups as Isometry Groups [PDF]

open access: yesTransactions of the American Mathematical Society, 1976
We show that given any finite group G of cardinality k + 1 k + 1 , there is a Riemannian sphere S k − 1 {S^{k - 1}} (imbeddable isometrically as a hypersurface in R

Complete Groups of Order $3p^6$ [PDF]

open access: yesAdvances in Group Theory and Applications, 2016
For each prime number $p$ with $3 | p − 1$, we construct a group of order $3p^5$, whose automorphism group is a complete group of order $3p^6$.

On σ-Residuals of Subgroups of Finite Soluble Groups

open access: yesMathematics, 2023
Let σ={σi:i∈I} be a partition of the set of all prime numbers. A subgroup H of a finite group G is said to be σ-subnormal in G if H can be joined to G by a chain of subgroups H=H0⊆H1⊆⋯⊆Hn=G where, for every j=1,⋯,n, Hj−1 is normal in Hj or Hj/CoreHj(Hj−1)
