In this paper, we give a characterization of digraphs Q, |Q|a parts per thousand currency sign4 such that the associated Hecke-Kiselman monoids H (Q) are finite. In general, a necessary condition for H (Q) to be a finite monoid is that Q is acyclic and its Coxeter components are Dynkin diagrams. We show, by constructing examples, that such conditions are not sufficient.

Abstract
In this paper, we give a characterization of digraphs Q, |Q|a parts per thousand currency sign4 such that the associated Hecke-Kiselman monoids H (Q) are finite. In general, a necessary condition for H (Q) to be a finite monoid is that Q is acyclic and its Coxeter components are Dynkin diagrams. We show, by constructing examples, that such conditions are not sufficient.File allegati a questo prodotto
