초록

We use Kazhdan-Lusztig bases of representations of the symmetric group to express Pfaans with entries (ai - aj )hi+j . In the case where the parameters ai are specialized to successive powers of q, and the hi are complete functions, we obtain the q-discriminant.

Abstract

We use Kazhdan-Lusztig bases of representations of the symmetric group to express Pfaans with entries (ai - aj )hi+j . In the case where the parameters ai are specialized to successive powers of q, and the hi are complete functions, we obtain the q-discriminant.
