Inertial endomorphisms of an abelian group [PDF]

open access: yes, 2013
We describe inertial endomorphisms of an abelian group $$A$$A, that is endomorphisms $$\varphi $$φ with the property $$|(\varphi (X)+X)/X|

Entropy on abelian groups [PDF]

open access: yesAdvances in Mathematics, 2016
We introduce the algebraic entropy for endomorphisms of arbitrary abelian groups, appropriately modifying existing notions of entropy. The basic properties of the algebraic entropy are given, as well as various examples. The main result of this paper is the Addition Theorem showing that the algebraic entropy is additive in appropriate sense with ...

On cosmall Abelian groups [PDF]

open access: yesJournal of Algebra, 2007
AbstractIt is a well-known homological fact that every Abelian group G has the property that Hom(G,−) commutes with direct products. Here we investigate the ‘dual’ property: an Abelian group G is said to be cosmall if Hom(−,G) commutes with direct products.

NagE: Non-Abelian Group Embedding for Knowledge Graphs

open access: yesInternational Conference on Information and Knowledge Management, 2020
We demonstrated the existence of a group algebraic structure hidden in relational knowledge embedding problems, which suggests that a group-based embedding framework is essential for designing embedding models.

Maximal abelian subgroups of the finite symmetric group [PDF]

open access: yesInternational Journal of Group Theory, 2021
‎Let $G$ be a group‎. ‎For an element $a\in G$‎, ‎denote by $\cs(a)$ the second centralizer of~$a$ in~$G$‎, ‎which is the set of all elements $b\in G$ such that $bx=xb$ for every $x\in G$ that commutes with $a$‎.

The Baer–Kaplansky Theorem for all abelian groups and modules

open access: yesBulletin of Mathematical Sciences, 2022
It is shown that the Baer–Kaplansky Theorem can be extended to all abelian groups provided that the rings of endomorphisms of groups are replaced by trusses of endomorphisms of corresponding heaps.

G-Tutte Polynomials and Abelian Lie Group Arrangements [PDF]

open access: yesInternational mathematics research notices, 2017
For a list $\mathcal{A}$ of elements in a finitely generated abelian group $\Gamma $ and an abelian group $G$, we introduce and study an associated $G$-Tutte polynomial, defined by counting the number of homomorphisms from associated finite abelian ...

The equivariant complex cobordism ring of a finite abelian group [PDF]

open access: yes, 2015
We compute the equivariant (stable) complex cobordism ring $(MU_G)_*$ for finite abelian groups $G$.

Classical simulations of Abelian-group normalizer circuits with intermediate measurements [PDF]

open access: yesQuantum information & computation, 2012
Quantum normalizer circuits were recently introduced as generalizations of Clifford circuits [1]: a normalizer circuit over a finite Abelian group G is composed of the quantum Fourier transform (QFT) over G, together with gates which compute quadratic ...

Universal abelian groups [PDF]

open access: yesIsrael Journal of Mathematics, 1995
We examine the existence of universal elements in classes of infinite abelian groups. The main method is using group invariants which are defined relative to club guessing sequences. We prove, for example: Theorem: For $n\ge 2$, there is a purely universal separable $p$-group in $\aleph_n$ if, and only if, $\cont\le \aleph_n$.
