摘要:

We compute the fibers of the canonical map from Weyl group elements to orbital varieties for a Lie algebra of typeB,C, orD. We also compute one irreducible component of the associated variety of any simple highest weight module in any classical type, thereby sharpening a result of Joseph and partially proving a conjecture of Tanisaki.
