A fast solution to the conjugacy problem in the four-strand braid group
Calvez, Matthieu; Wiest, Bert (De Gruyter, 2014-09)We present an algorithm for solving the conjugacy search problem in the fourstrand braid group. The computational complexity is cubic with respect to the braid length.

A positive proportion of elements of mapping class groups is pseudo-Anosov
Cumplido Cabello, María; Wiest, Bert (Wiley, 2018-03-28)In the Cayley graph of the mapping class group of a closed surface, with respect to any generating set, we look at a ball ...

Acylindrical hyperbolicity and Artin-Tits groups of spherical type
Calvez, Matthieu; Wiest, Bert (Springer, 2017)We prove that, for any irreducible Artin-Tits group of spherical type G, the quotient of G by its center is acylindrically ...

Fast algorithmic Nielsen-Thurston classification of four-strand braids
Calvez, Matthieu; Wiest, Bert (World Scientific Publishing, 2012-04)We give an algorithm which decides the Nielsen-Thurston type of a given four-strand braid. The complexity of our algorithm ...

Reducible braids and Garside theory
González-Meneses López, Juan; Wiest, Bert (Geometry & Topology Publications, 2011)We show that reducible braids which are, in a Garside-theoretical sense, as simple as possible within their conjugacy ...
