Irreducible representations of Hecke-Kiselman monoids

Magdalena Wiertel

Let $K [H K_{Θ}]$ denote the Hecke-Kiselman algebra of a finite oriented graph $Θ$ over an algebraically closed field $K$ . All irreducible representations, and the corresponding maxima…

On the radical of a Hecke-Kiselman algebra

Jan Okniński, Magdalena Wiertel

The Hecke-Kiselman algebra of a finite oriented graph $Θ$ over a field $K$ is studied. If $Θ$ is an oriented cycle, it is shown that the algebra is semiprime and its central locali…

Combinatorics and structure of Hecke-Kiselman algebras

Jan Okniński, Magdalena Wiertel

Hecke-Kiselman monoids $HK_{Θ}$ and their algebras $K [HK_{Θ}]$ , over a field $K$ , associated to finite oriented graphs $Θ$ are studied. In the case $Θ$ is a cycle of…
