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.

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 ...

Conjugacy stability of parabolic subgroups of Artin-Tits groups of spherical type
Calvez, Matthieu; Cisneros de la Cruz, Bruno A.; Cumplido Cabello, María (Elsevier, 2020-08-15)We give a complete classification of conjugacy stable parabolic subgroups of Artin-Tits groups of spherical type. This ...

Dual Garside structure and reducibility of braids
Calvez, Matthieu (Elsevier, 2012-04-15)Benardete, Gutierrez and Nitecki showed an important result which relates the geometrical properties of a braid, as a ...

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 ...

Fast Nielsen-Thurston classification of braids
Calvez, Matthieu (Mathematical Sciences Publishers, 2014)We prove the existence of an algorithm that solves the reducibility problem in braid groups and runs in quadratic time with respect to the braid length for any fixed braid index.
