Symmetry, Integrability and Geometry: Methods and Applications (Apr 2010)
Monomial Crystals and Partition Crystals
Abstract
Recently Fayers introduced a large family of combinatorial realizations of the fundamental crystal B(Λ_0) for ^sl_n, where the vertices are indexed by certain partitions. He showed that special cases of this construction agree with the Misra-Miwa realization and with Berg's ladder crystal. Here we show that another special case is naturally isomorphic to a realization using Nakajima's monomial crystal.
