The Conjugacy Problem in Small Gaussian Groups

Small Gaussian groups are a natural generalization of spherical Artin groups, namely groups of fractions of monoids in which the existence of least common multiples is kept as an hypothesis, but the relations between the generators are not supposed to necessarily be of Coxeter type. We show here how to extend the Elrifai–Morton solution for the conjugacy problem in braid groups to every small Gaussian group.
