Semigroup identities and varieties of plactic monoids

Year: 2025
Type: article
Abstract: In this paper, we study the semigroup identities satisfied by finite rank plactic monoids. We find a new set of semigroup identities of the plactic monoid of rank n for [Formula: see text], which are shorter than those previously known when [Formula: see text]. Using these semigroup identities we show that for all [Formula: see text], the plactic monoid of rank n satisfies a semigroup identity not satisfied by the semigroup of [Formula: see text] upper triangular tropical matrices. We then prove that the plactic monoid of rank n generates a different semigroup variety for each rank n.
