ON AUTOMORPHISMS AND ENDOMORPHISMS OF CC GROUPS

open access: hybridProceedings of the YSU A: Physical and Mathematical Sciences, 2018
We consider the automorphisms description question for the semigroups End($G$) of a group $G$ having only cyclic centralizers (CC) of nontrivial elements. In particular, we prove that each member of the automorphism group Aut($G$) of a group $G$ from this class is uniquely determined by its action on the elements from the subgroup of inner ...

Endomorphism Algebras and Automorphism Groups of certain Complex Tori [PDF]

open access: green, 2022
We study the endomorphism algebra, the automorphism group and the Hodge group of complex tori of complex tori, whose second rational cohomology group enjoys a certain Hodge property introduced by F. Campana.

Endomorphism and automorphism graphs of finite groups [PDF]

open access: green
Let $G$ be a group. The directed endomorphism graph, $\dend(G)$ of $G$ is a directed graph with vertex set $G$ and there is a directed edge from the vertex $a$ to the vertex $b$ if $a \neq b$ and there exists an endomorphism on $G$ mapping $a$ to $b$. The endomorphism graph, $\uend(G)$ is the corresponding undirected simple graph.

On automorphism groups and endomorphism rings of abelian 𝑝-groups [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1975
Let A A be a noncyclic abelian p p -group where p ⩾ 5 p \geqslant 5 , and let p ∞ A {p^\infty }A be the maximal divisible subgroup of A A . It is shown that A

Automorphism tower problem and semigroup of endomorphisms for free Burnside groups [PDF]

open access: green, 2013
We have proved that the group of all inner automorphisms of the free Burnside group $B(m,n)$ is the unique normal subgroup in $Aut(B(m,n))$ among all its subgroups, which are isomorphic to free Burnside group $B(s,n)$ of some rank $s$ for all odd $n\ge1003$ and $m>1$.

Crossed Products by Semigroups of Endomorphisms and Groups of Partial Automorphisms [PDF]

open access: bronzeCanadian Mathematical Bulletin, 2003
AbstractWe consider a class (A; S; α) of dynamical systems, where S is an Ore semigroup and α is an action such that each αs is injective and extendible (i.e. it extends to a non-unital endomorphism of the multiplier algebra), and has range an ideal of A.

Endomorphism near-rings of 𝑝-groups generated by the automorphism and inner automorphism groups [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1993
The purpose of this paper is to investigate the equality of the endomorphism near-rings generated by the automorphism group and inner automorphism group of a nonabelian p p -group G G . If the automorphism group of G G is not a p p -group, we find that these near-rings are different ...

A Hitchhiker's Guide to Endomorphisms and Automorphisms of Cuntz Algebras

open access: greenRendiconti di Matematica e delle Sue Applicazioni, 2021
In this survey paper, the authors discuss various aspects of Cuntz algebras, concentrating primarily on endomorphisms and automorphisms. The authors nicely summarize many known results and provide an extensive list of open problems. Chapter 1 is an overview of the paper.
