A cluster algebra approach to presentations of the monoid of uniform block permutations

Abstract

We describe the mutation class of a certain quiver with a frozen vertex and associate these quivers with potentials appearing in our mutation class to presentations of the monoid \({\mathscr {P}}_{n+1}\) of uniform block permutations on the set \(\{1,2,\ldots , n+1\}\). Some classical and known presentations of \({\mathscr {P}}_{n+1}\), including FitzGerald’s presentation and Everitt and Fountain’s presentation, are recovered.
