GRAW02 - Computational and algorithmic methods Extending representation theory from finite groups to finite semigroups brings interesting challenges, combinatorics, and applications. Almost a decade ago, I proposed an algorithm to compute the Cartan Matrix of a semigroup algebra—a combinatorial invariant that contains information on how projective modules are built from simple modules. It boils down to computing with finite semigroups, characters of groups, and combinatorics. Despite this relative simplicity, and much to my embarrassment, a full production-grade implementation is only finally in reach.
