Abstract:
Crystals provide combinatorial models for representations of
semisimple Lie algebras. For sl_n, the semistandard Young tableaux
provide a convenient way for describing crystals. Another geometric
description of these crystals is provided by components of n-step
Springer fibres. These geometric and combinatorial descriptions are
linked by a natural bijection. A convenient generalization of Young
tableaux is provided by the theory of reverse plane partitions on
minuscule heaps. I will explain how these RPPs are naturally in
bijection with components of quiver Grassmannians for preprojective
algebra modules.
