Abstract

We describe a constructive, cubic time solution to the conjugacy problem in Artin groups of extra-large type, which was proved solvable in those groups in \cite{AppelSchupp83}. We use results from \cite{HoltRees,CHR} that characterise geodesic words in those groups, as well as the description of conjugacy between elements involving three or more generators that is given in \cite{AppelSchupp83}. \
