Title: PBW bases and marginally large tableaux in types B and C,
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.
