Homomorphic Encoders of Profinite Abelian Groups II

open access: yesAxioms, 2022
Let {Gi:i∈N} be a family of finite Abelian groups. We say that a subgroup G≤∏i∈NGi is order controllable if for every i∈N, there is ni∈N such that for each c∈G, there exists c1∈G satisfying c1|[1,i]=c|[1,i], supp(c1)⊆[1,ni], and order (c1) divides order (

A note on abelian groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1953
Vijayaraghavan and Chowla [2] have proved the following result. If n=2 or has no primitive root, then there exist suitable reduced residue systems rl, r2, , * * , rh and sl, S2 , . * Sh, where h= 4(n), such that risi, r2s2, * , rhsh is also a complete residue system (mod n).

More Abelian groups with free duals [PDF]

open access: yes, 2011
In answer to a question of A. Blass, J. Irwin and G. Schlitt, a subgroup G of the additive group Z^{\omega} is constructed whose dual, Hom(G,Z), is free abelian of rank 2^{\aleph_0}.

A Characterization of Abelian Groups [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
Let G G be a group and let k > 2 k > 2 be an integer such that ( k 3 − k ) > | G | / 2 ({k^3} - k) > |G|

Poor and pi-poor Abelian groups [PDF]

open access: yes, 2015
In this paper, poor abelian groups are characterized. It is proved that an abelian group is poor if and only if its torsion part contains a direct summand isomorphic to , where P is the set of prime integers.

Annihilating Graph of Abelian Groups

open access: yesپژوهش‌های ریاضی, 2021
In [18], the author associated a graph to an R -module M which is precisely a generalization of annihilating ideal graph of a commutative ring, see [15] and [16]. Inasmuch as Abelian groups are precisely Z-modules, in this paper we relate an annihilating

Convergent nets in abelian topological groups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
A net in an abelian group is called a T-net if there exists a Hausdorff group topology in which the net converges to 0. This paper describes a fundamental system for the finest group topology in which the net converges to 0.

Characterized Subgroups of Topological Abelian Groups

open access: yesAxioms, 2015
A subgroup H of a topological abelian group X is said to be characterized by a sequence v = (vn) of characters of X if H = {x ∈ X : vn(x) → 0 in T}. We study the basic properties of characterized subgroups in the general setting, extending results known ...

Haag duality for Kitaev's quantum double model for abelian groups [PDF]

open access: yes, 2014
We prove Haag duality for cone-like regions in the ground state representation corresponding to the translational invariant ground state of Kitaev’s quantum double model for finite abelian groups.
