Crystals for Demazure Modules of Classical Affine Lie Algebras
arXiv:q-alg/9707014
Abstract
We study, in the path realization, crystals for Demazure modules of affine Lie algebras of types . We find a special sequence of affine Weyl group elements for the selected perfect crystal, and show if the highest weight is $l\La_0$, the Demazure crystal has a remarkably simple structure.
