Conjugacy geodesics and growth in dihedral Artin groups

Group Theory 2025-02-25 v3

Abstract

In this paper we describe conjugacy geodesic representatives in any dihedral Artin group G(m)G(m), m3m\geq 3, which we then use to calculate asymptotics for the conjugacy growth of G(m)G(m), and show that the conjugacy growth series of G(m)G(m) with respect to the `free product' generating set {x,y}\{x, y\} is transcendental. We prove two additional properties of G(m)G(m) that connect to conjugacy, namely that the permutation conjugator length function is constant, and that the falsification by fellow traveler property (FFTP) holds with respect to {x,y}\{x, y\}. These imply that the language of all conjugacy geodesics in G(m)G(m) with respect to {x,y}\{x, y\} is regular.
