Jucys-Murphy elements and Grothendieck groups for generalized rook monoids
Abstract
We consider a tower of generalized rook monoid algebras over the field of complex numbers and observe that the Bratteli diagram associated to this tower is a simple graph. We construct simple modules and describe Jucys-Murphy elements for generalized rook monoid algebras. Over an algebraically closed field of positive characteristic , utilizing Jucys-Murphy elements of rook monoid algebras, for we define the corresponding -restriction and -induction functors along with two extra functors. On the direct sum of the Grothendieck groups of module categories over rook monoid algebras over , these functors induce an action of the tensor product of the universal enveloping algebra and the monoid algebra of the bicyclic monoid . Furthermore, we prove that is isomorphic to the tensor product of the basic representation of and the unique infinite-dimensional simple module over , and also exhibit that is a bialgebra. Under some natural restrictions on the characteristic of , we outline the corresponding result for generalized rook monoids.
