Finite Dimensional Representations of Khovanov-Lauda-Rouquier algebras I: Finite Type
Abstract
We classify simple representations of Khovanov-Lauda-Rouquier algebras in finite type. The classification is in terms of a standard family of representations that is shown to yield the dual PBW basis in the Grothendieck group. Finally, we prove a conjecture describing the global dimension of these algebras.
