Generic Homeomorphisms with Shadowing of One-Dimensional Continua

open access: yesAxioms, 2019
In this article, we show that there are homeomorphisms of plane continua whose conjugacy class is residual and have the shadowing property.

Countably recognizable classes of groups with restricted conjugacy classes [PDF]

open access: yesInternational Journal of Group Theory, 2018
A group class ${ X}$ is said to be countably recognizable if a group belongs to ${X}$ whenever all its countable subgroups lie in ${X}$‎. ‎It is proved here that most of the relevant classes of groups defined by restrictions on the conjugacy classes are ...

ON CONJUGACY CLASSES OF CLOSED SUBGROUPS

open access: yesDemonstratio Mathematica, 1986
The note is devoted to proving the following result: if G is a compact Lie group then the set of conjugacy classes of its closed subgroups is countable. The proof given uses purely topological methods and is based on classical facts concerning actions of compact Lie groups including Mostow-Palais theorem on equivariant imbeddings of actions of a ...

TWISTED CONJUGACY CLASSES IN WREATH PRODUCTS [PDF]

open access: yesInternational Journal of Algebra and Computation, 2006
Let G be a finitely generated abelian group and G ≀ ℤ be the wreath product. In this paper, we classify all such groups G for which every automorphism of G ≀ ℤ has infinitely many twisted conjugacy classes.

On functional moduli of surface flows

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2020
Currently, an complete topological classification has been obtained with respect to the topological equivalence of Morse-Smale flows, [9, 7], as well as their generalizations of Ω-stable flows on closed surfaces, [4].

Character expansiveness in finite groups [PDF]

open access: yesInternational Journal of Group Theory, 2013
We say that a finite group $G$ is conjugacy expansive if for anynormal subset $S$ and any conjugacy class $C$ of $G$ the normalset $SC$ consists of at least as many conjugacy classes of $G$ as$S$ does.

Complete parts and subhypergroups in reversible regular hypergroups

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
In this paper we analyse the center and centralizer of an element in the context of reversible regular hypergroups, in order to obtain the class equation in regular reversible hypergroups, by using complete parts.

Conjugacy classes of Renner monoids

open access: yesJournal of Algebra, 2013
A reference ([13]) and Corollary 4.5 are added to show the connection between the result in Theorem 4.4 of the previous version and the results in [13]. A paragraph on page 12 is new to show that Theorem 4.4 can also be deduced from the results in [13].

The Lengths of Certain Real Conjugacy Classes and the Related Prime Graph

open access: yesMathematics, 2021
Let G be a finite group. In this paper, we study how certain arithmetical conditions on the conjugacy class lengths of real elements of G influence the structure of G. In particular, a new type of prime graph is introduced and studied. We obtain a series
