Elliptic Weyl group elements and unipotent isometries with p=2

open access: yes, 2011
Let G be a classical group over an algebraically closed field of characteristic 2 and let C be an elliptic conjugacy class in the Weyl group. In a previous paper the first named author associated to C a unipotent conjugacy class \Phi(C) in G.

Boundedly finite conjugacy classes of tensors

open access: yesInternational Journal of Group Theory, 2019
Let $n$ be a positive integer and let $G$ be a group. We denote by $ν(G)$ a certain extension of the non-abelian tensor square $G \otimes G$ by $G \times G$. Set $T_{\otimes}(G) = \{g \otimes h \mid g,h \in G\}$. We prove that if the size of the conjugacy class $\left |x^{ν(G)} \right| \leq n$ for every $x \in T_{\otimes}(G)$, then the second derived ...

Cryptanalysis of matrix conjugation schemes

open access: yesJournal of Mathematical Cryptology, 2014
In this paper we cryptanalyze two protocols: the Grigoriev–Shpilrain authentication protocol and a public key cryptosystem due to Wang, Wang, Cao, Okamoto and Shao.

Simple dynamical systems

open access: yesApplied General Topology, 2019
In this paper, we study the class of simple systems on R induced by homeomorphisms having finitely many non-ordinary points. We characterize the family of homeomorphisms on R having finitely many non-ordinary points upto (order) conjugacy.

A note on groups with many locally supersoluble subgroups [PDF]

open access: yesInternational Journal of Group Theory, 2015
It is proved here that if G is a locally graded group satisfying the minimal condition on subgroups which are not locally supersoluble, then G is either locally supersoluble or a \vCernikov group.

On the representation theory of the alternating groups [PDF]

open access: yesInternational Journal of Group Theory, 2013
We present the basic results on the representation theory of the alternating groups. Our approach is based on Clifford theory.

Generalized Strain and Stress Measures: Critical Survey and New Results

open access: yesEngineering Transactions, 1991
Four basic principles: objectivity, isotropy, consistency and regularity are proposed to res tri.et the concepts of generalized strain and (more originally) of generalized stress.
