DESCRIPTION:Title: Quiver presentations for Hecke categories and KLR alge
 bras\n\nAbstract: We discuss the algebraic structure of KLR algebras by 
 way of the diagrammatic Hecke categories of maximal parabolics of finite
  symmetric groups. Combinatorics (in the shape of Dyck tableaux) plays a
  huge role in understanding the structure of these algebras. Instead of 
 looking only at the sets of Dyck tableaux (which enumerate the p-Kazhdan
 -Lusztig polynomials) we look at the relationships for passing between t
 hese Dyck tableaux. In fact\, this “meta-Kazhdan-Lusztig combinatorics” 
 is sufficiently rich as to completely determine the complete Ext-quiver 
 and relations of these algebras.
