Demazure Crystals, Kirillov-Reshetikhin Crystals, and the Energy Function
Demazure Crystals, Kirillov-Reshetikhin Crystals, and the Energy Function
It has previously been shown that, at least for non-exceptional Kac-Moody Lie algebras, there is a close connection between Demazure crystals and tensor products of Kirillov-Reshetikhin crystals. In particular, certain Demazure crystals are isomorphic as classical crystals to tensor products of Kirillov-Reshetikhin crystals via a canonically chosen isomorphism. Here we …
