PBW Bases and Marginally Large Tableaux in Types B and C
Published online by Cambridge University Press: 04 January 2019
Abstract
We explicitly describe the isomorphism between two combinatorial realizations of Kashiwara’s infinity crystal in types B and C. The first realization is in terms of marginally large tableaux and the other is in terms of Kostant partitions coming from PBW bases. We also discuss a stack notation for Kostant partitions which simplifies that realization.
