Heaps, crystals, and preprojective algebra modules

Anne Dranowski, Balazs Elek, Joel Kamnitzer +1

Fix a simply-laced semisimple Lie algebra. We study the crystal $B(n\lambda )$, were $\lambda$ is a dominant minuscule weight and $n$ is a natural number. On one hand, $B(n\lambda )$ can be realized…
