Deformations of Weyl's Denominator Formula

Abstract
English
We introduce a series of conjectured identities that deform Weyl's denominator formula and generalize Tokuyama's formula to other root systems. These conjectures generalize a number of well-known results due to Okada. We also prove a related result for $B'_n$ that generalizes a theorem of Simpson.

Nous proposons une série de conjectures qui sont des déformations de la formule dénominateur de Weyl et qui généralisent la formule de Tokuyama à d’autres systèmes de racines. Ces résultats sont des généralisations de théorèmes bien connus dus à Okada. Nous donnons aussi la preuve d’un résultat pour $B'_n$ qui est une généralisation d’un théorème de Simpson.
