Cryptanalysis of some nonabelian group-based key exchange protocols [PDF]

open access: yesJournal of Mathematical Cryptology
In the recently emerging field of nonabelian group-based cryptography, a prominently used one-way function is the conjugacy search problem (CSP), and two important classes of platform groups are polycyclic and matrix groups. In this paper, we discuss the

Multicomponent KP type hierarchies and their reductions, associated to conjugacy classes of Weyl groups of classical Lie algebras [PDF]

open access: yesJournal of Mathematics and Physics, 2023
This, to a large extent, expository paper describes the theory of multicomponent hierarchies of evolution equations of XKP type, where X = A, B, C, or D, and AKP = KP and their reductions, associated with the conjugacy classes of the Weyl groups of ...

Conjugacy classes of big mapping class groups [PDF]

open access: yesJournal of the London Mathematical Society, 2021
We describe the topological behavior of the conjugacy action of the mapping class group of an orientable infinite‐type surface Σ$\Sigma$ on itself by proving that: (1)all conjugacy classes of Map(Σ)$\operatorname{Map}(\Sigma )$ are meager for every Σ ...

New lower bounds for the number of conjugacy classes in finite nilpotent groups [PDF]

open access: yesInternational Journal of Group Theory, 2022
P‎. ‎Hall's classical equality for the number of conjugacy classes in $p$-groups yields $k(G) \ge (3/2) \log_2 |G|$ when $G$ is nilpotent‎. ‎Using only Hall's theorem‎, ‎this is the best one can do when $|G| = 2^n$‎. ‎Using a result of G.J‎.

Reality Properties of Finite Simple Orthogonal Groups [PDF]

open access: yesAdvances in Group Theory and Applications, 2023
We prove several reality properties for finite simple orthogonal groups. For any prime power q and m ≥ 1, we show that all real conjugacy classes are strongly real in the simple groups PΩ±(4m + 2, q), m ≥ 1, except in the case PΩ−(4m + 2, q) with q ≡ 3 ...

Conjugacy classes contained in normal subgroups: an overview [PDF]

open access: yesInternational Journal of Group Theory, 2018
We survey known results concerning how the conjugacy classes contained in a normal subgroup and their sizes exert an influence on the normal structure of a finite group.

On the Regular Power Graph on the Conjugacy Classes of Finite Groups [PDF]

open access: yesMathematics Interdisciplinary Research, 2018
The (undirected) power graph on the conjugacy classes PC(G) of a group G  is a simple graph in which the vertices are the conjugacy classes of G and two distinct vertices C and C' are adjacent in PC(G) if one is a subset of a power of the other.

Twisted conjugacy in direct products of groups [PDF]

open access: yesCommunications in Algebra, 2021
Given a group G and an endomorphism of G, two elements are said to be -conjugate if for some The number of equivalence classes for this relation is the Reidemeister number of The set is called the Reidemeister spectrum of G.
