[PDF][PDF] On Kiselman quotients of 0-Hecke monoids
O Ganyushkin, V Mazorchuk - International Electronic Journal of …, 2011 - dergipark.org.tr
Combining the definition of 0-Hecke monoids with that of Kiselman semigroups, we define
what we call Kiselman quotients of 0-Hecke monoids associated with simply laced Dynkin …

Koszul duality for monoids and the operad of enriched rooted trees
MA Méndez - Advances in Applied Mathematics, 2010 - Elsevier
We introduce here the notion of Koszul duality for monoids in the monoidal category of
species with respect to the ordinary product. To each Koszul monoid we associate a class of …
