Représentation par des transvections des groupes d'Artin–Tits
In a recent article, C. Kassel and C. Reutenauer studied the connection between the4 strand braid group and Sturmian morphisms in word combinatorics. The aim of the current work is to extend this
L'INTERPRÉTATION MATRICIELLE DE LA THÉORIE DE MARKOFF CLASSIQUE
On explicite l'approche de Cohn (1955) de la theorie de Markoff. On montre en particulier comment l'arbre complet des solutions de l'equation diophantienne associee apparasit comme quotient du

Let $F_n$ be the free group on $n$ generators. Consider the group $IA_n$ of automorphisms of $F_n$ acting trivially on its abelianization. There are two canonical filtrations on $IA_n$: the 1st one
Quotient groups of IA-automorphisms of a free group of rank 3
TLDR
It is proved that, for any positive integer c, the quotient group γc(M3)/γc+1(M2) of the lower central series of the McCool group M3 is isomorphic to two copies of the quotients group εγc(F3/γc-1(F4) of a free group F3 of rank 3 as ℤ-modules.
The complex of partial bases for Fn and finite generation of the Torelli subgroup of Aut (Fn)
We study the complex of partial bases of a free group, which is an analogue for Aut(Fn) of the curve complex for the mapping class group. We prove that it is connected and simply connected, and we
Relative Weight Filtrations on Completions of Mapping Class Groups
This paper gives an exposition of relative weight filtrations on completions of mapping class groups associated to a stable degeneration of marked genus g curves. These relative weight filtrations
Linear Representations of the Automorphism Group of a Free Group
Abstract.Let Fn be the free group on n ≥ 2 elements and Aut(Fn) its group of automorphisms. In this paper we present a rich collection of linear representations of Aut(Fn) arising through the action
Actions of the homeotopy group of an orientable 3-dimensional handlebody
The actions of the homeotopy group of an orientable 3-dimensional handlebody on the fundamental group and on the first homology group are completely determined. As an application generators are
