Conjugacy in Abstract Semigroups, Transformation and Diagram Monoids, and Conjugacy Growth

João Araújo, Wolfram Bentz, Michael Kinyon +3

We study conjugacy relations on semigroups and monoids, focusing on the relation $a \cfn b$, defined by the existence of $g,h\in S^1$ such that $ag=gb$, $bh=ha$, $hag=b$, an…
