On the occurrence of elementary abelian $p$-groups as the Schur multiplier of non-abelian $p$-groups

open access: yesComptes Rendus. Mathématique, 2023
We prove that every elementary abelian $p$-group, for odd primes $p$, occurs as the Schur multiplier of some non-abelian finite $p$-group.

Commutativity Degree of Certain Finite AC-Groups [PDF]

open access: yesMathematics Interdisciplinary Research, 2021
For a finite group G, the probability of two elements of G that commute is the commutativity degree of G denoted by P(G). As a matter of fact, if C = {(a; b) ∈ G×G | ab = ba}, then P(G) = |C|/|G|2 .

THE CYCLIC DECOMPOSITION OF THE FACTOR GROUP CF(Dnh,Z)/R(Dnh) WHEN N IS AN ODD NUMBER

open access: yesJournal of Kufa for Mathematics and Computer, 2010
For fixed positive integer n³3 ,let Dn be the dihedral group, Dnh= Dn ÏC2 and cf(Dnh,Z) be the abelian group of Z-valued class functions of the group Dnh .The intersection of cf(Dnh,Z) with the group of all generalized characters of Dnh , R(Dnh) is a ...

On the Norm of the Abelian p-Group-Residuals

open access: yesMathematics, 2021
Let G be a group. Dp(G)=⋂H≤GNG(H′(p)) is defined and, the properties of Dp(G) are investigated. It is proved that Dp(G)=P[A], where P=D(P) is the Sylow p-subgroup and A=N(A) is a Hall p′-subgroup of Dp(G), respectively.

On nilpotent but not abelian groups and abelian but not cyclic groups

open access: yesJournal of Number Theory, 1988
Using general sieve-type methods of number theory and certain density estimates for prime numbers, the authors derive asymptotic formulae for \(A(n)-C(n)\) and \(N(n)-A(n)\), where \(A(n)=\#\{m\leq n:\) every group of order \(m\) is abelian\(\},\) \(C(n)=\#\{m\leq n:\) every group of order \(m\) is cyclic\(\}\), and \(N(n)=\#\{m\leq n:\) every group of

Renormalization of an Abelian tensor group field theory: solution at leading order [PDF]

open access: yes, 2015
A bstractWe study a just-renormalizable tensorial group field theory of rank six with quartic melonic interactions and Abelian group U(1). We introduce the formalism of the intermediate field, which allows a precise characterization of the leading order ...

Complementary dual abelian codes in group algebras of some finite abelian groups [PDF]

open access: yesITM Web of Conferences
Linear complementary dual codes have become an interesting sub-family of linear codes over finite fields since they can be practically applied in various fields such as cryptography and quantum error-correction. Recently, properties of complementary dual

On groups and counter automata [PDF]

open access: yes, 2006
We study finitely generated groups whose word problems are accepted by counter automata. We show that a group has word problem accepted by a blind n-counter automaton in the sense of Greibach if and only if it is virtually free abelian of rank n; this ...

Abelian Galois groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1959
The question of the existence of noninner, nonouter Abelian Galois groups of noncommutative rings seems not to have been considered previously. Amitsur [1 ] may have come closest when he constructed noninner, nonouter cyclic division ring extensions.

General Matter Coupled N=4 Gauged Supergravity in Five Dimensions [PDF]

open access: yes, 2001
We construct the general form of matter coupled N=4 gauged supergravity in five dimensions. Depending on the structure of the gauge group, these theories are found to involve vector and/or tensor multiplets. When self-dual tensor fields are present, they
