Arcis, Diego. "Ordering Garside groups." Thesis, Bourgogne Franche-Comté, 2017. http://www.theses.fr/2017UBFCK049/document.
Full textWe introduce a condition on Garside groups that we call Dehornoy structure. An iteration of such a structure leads to a left order on the group. We show conditions for a Garside group to admit a Dehornoy structure, and we apply these criteria to prove that the Artin groups of type A and I2(m), m ≥ 4, have Dehornoy structures. We show that the left orders on the Artin groups of type A obtained from their Dehornoy structures are the Dehornoy orders. In the case of the Artin groups of type I2(m), m ≥ 4, we show that the left orders derived from their Dehornoy structures coincide with the orders obtained from embeddings of the groups into braid groups

Full textThe main purpose of this thesis is the study of combinatorial problems in group theory. Given a group defined by generators and relations, there are several combinatorial problems that we can state , such as the word problem, the conjugacy problem , the membership problem , and the problem of finding generating sets of centralizers. We present a solution to the conjugacy problem for Garside groups as well as an algorithm which computes a generating set for centralizers in Garside groups. Let G be a group endowed with a solution to the conjugacy problem and with an algorithm which computes a generating set of the centralizer of any element in G. We give conditions to a subgroup H of G under which we give a solution to the conjugacy problem in H. Let A be a spherical type Artin group, which is not necessarily irreductible, and let CA denote its associated coloured Artin group. We prove that CA is a characteristic subgroup

Full textIn the first part of this thesis we study the genericity conjecture: In the Cayley graph of the mapping class group of a closed surface we look at a ball of large radius centered on the identity vertex, and at the proportion of pseudo-Anosov vertices among the vertices in this ball. The genericity conjecture states that this proportion should tend to one as the radius tends to infinity. We prove that it stays bounded away from zero and prove similar results for a large class of subgroups of the mapping class group. We also present analogous results for Artin--Tits groups of spherical type, knowing that in this case being pseudo-Anosov is analogous to being a loxodromically acting element. In the second part we provide results about parabolic subgroups of Artin-Tits groups of spherical type: The minimal standardizer of a curve on a punctured disk is the minimal positive braid that transforms it into a round curve. We give an algorithm to compute it in a geometrical way. Then, we generalize this problem algebraically to parabolic subgroups of Artin--Tits groups of spherical type. We also show that the intersection of two parabolic subgroups is a parabolic subgroup and that the set of parabolic subgroups forms a lattice with respect to inclusion. Finally, we define the simplicial complex of irreducible parabolic subgroups, and we propose it as the analogue of the curve complex for mapping class groups

Full textWe define geodesic normal forms for the general series of complex reflection groups G(de,e,n). This requires the elaboration of a combinatorial technique in order to determine minimal word representatives and to compute the length of the elements of G(de,e,n) over some generating set. Using these geodesic normal forms, we construct intervals in G(e,e,n) that give rise to Garside groups. Some of these groups correspond to the complex braid group B(e,e,n). For the other Garside groups that appear, we study some of their properties and compute their second integral homology groups. Inspired by the geodesic normal forms, we also define new presentations and new bases for the Hecke algebras associated to the complex reflection groups G(e,e,n) and G(d,1,n) which lead to a new proof of the BMR (Broué-Malle-Rouquier) freeness conjecture for these two cases. Next, we define a BMW (Birman-Murakami-Wenzl) and Brauer algebras for type (e,e,n). This enables us to construct explicit Krammer's representations for some cases of the complex braid groups B(e,e,n). We conjecture that these representations are faithful. Finally, based on our heuristic computations, we propose a conjecture about the structure of the BMW algebra

Full text. This work deals with braid based cryptography. We study the conjugacy search problem and the cycling problem presented by K. H. Ko, S. J. Lee and al. At CRYPTO 2000 (LNCS 1880) in New public-key cryptosystem using braid groups. On the one hand, we give a polynomial time algorithm to inverse the cycling function in Garside group which are a generalization of braid groups ; that allows to solve practically the cycling problem. On the other hand, our work on the conjugacy search problem and its variants emphasizes the choice of random generator of braids in protocols. We give an algorithm that factorizes the secret into a divisor and a multiple. That allows to define two new conjugacy instances with shorter secrets. Moreover, we exploit the fact that a braid group has two distinct Garside structures to improve the efficiency of the reduction. We observe that the choice of random generators influences greatly the security of an instance and we give several constructive and encouraging elements for further research in the design of good random generator of braids

Full textArtin-Tits and Garside groups, two generalizations of braid groups, are both particular types of preGarside groups. In this thesis, we extend some results proved for braid groups, to Artin-Tits, Garside, and preGarside groups. First, we focus on the submonoids of fixed points and periodic points of endomorphisms of preGarside, Garside and Artin-Tits monoids. We show that these submonoids inherit, under some conditions, the structure of the ambient group. Then, we study some metrics over these same monoids. We compare these distances, show some equivalences and non-equivalences between them in general and in some particular cases, and then we provide a characterization of those endomorphisms of Artin-Tits monoids that are contractions. Finally, we calculate the double centralizer of any parabolic subgroup of any Artin-Tits group of spherical type

Full textWe study a certain monoid specified by a presentation, denoted P, that is a hybrid of the classical presentation of the infinite braid monoid and of the presentation of Thompson’s monoid. To this end, we use several approaches. First, we describe a convergent rewrite system for P, which provides in particular a solution to the word problem, and makes the hybrid monoid reminiscent of Thompson’s monoid. Next, on the shape of the braid monoid, we use the factor reversing method to analyze the divisibility relation, and show in particular that the hybrid monoid admits cancellation and conditional right lcms. Then, we study Garside combinatorics of the hybrid: for every integer n, we introduce an element ∆(n) as the right lcm of the first (n−1) atoms, and one investigates the left divisors of the elements ∆(n), called simple elements. The main results are a counting of the left divisors of ∆(n) and a characterization of the normal forms of simple elements. We conclude with the construction of several representations of the hybrid monoid in various monoids, in particular a representation in a monoid of matrices whose entries are Laurent polynomials, which we conjecture could be faithful
