Convolution Algebras for Finite Reductive Monoids

Jared Marx-Kuo, Vaughan McDonald, John M. O'Brien +1

For an arbitrary finite monoid $M$ and subgroup $K$ of the unit group of $M$ , we prove that there is a bijection between irreducible representations of $M$ with nontrivial $K$ -fixe…

Characters of Renner Monoids and Their Hecke Algebras

Andy Hardt, Jared Marx-Kuo, Vaughan McDonald +2

This paper gives a general algorithm for computing the character table of any Renner monoid Hecke algebra, by adapting and generalizing techniques of Solomon used to study the rook…
