Abstract

We investigate the manner in which the partition monoid Pn and algebra Pξ n may be presented by generators and relations. Making use of structural properties of Pn, as well as presentations for several key submonoids, we obtain a number of presentations for Pn, including that given (without a complete proof) by Halverson and Ram in 2005. We then conclude by showing how each of these presentations gives rise to an algebra presentation for Pnξ .
