On the topological conjugacy of two-dimensional homogeneous inner mappings

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2015
For a class of branched coverings of the two-dimensional sphere the criterion of the topological conjugacy is given and some properties are listed.

On spherical twisted conjugacy classes [PDF]

open access: yesTransformation Groups, 2012
Let G be a simple algebraic group over an algebraically closed field of good odd characteristic, and let theta be an automorphism of G arising from an involution of its Dynkin diagram. We show that the spherical theta-twisted conjugacy classes are precisely those intersecting only Bruhat cells corresponding to twisted involutions in the Weyl group.

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 ...

COUNTING CONJUGACY CLASSES

open access: yesBulletin of the London Mathematical Society, 2005
Summary: This paper proves the rationality of Poincaré series whose coefficients are defined using the number of conjugacy classes in a system of finite groups defined as finite images of linear groups over \(\mathbb{Z}_p\) modulo natural congruence subgroups.

Conjugacy in normal subgroups of hyperbolic groups

open access: yes, 2012
Let N be a finitely generated normal subgroup of a Gromov hyperbolic group G. We establish criteria for N to have solvable conjugacy problem and be conjugacy separable in terms of the corresponding properties of G/N.

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].

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.

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.
