Generalized Verma modules, b-functions of semi-invariants and duality for twisted 𝒟-modules on generalized flag manifolds
Comptes Rendus. Mathématique, Volume 335 (2002) no. 2, pp. 111-116.

Let G be a connected semisimple algebraic group over , P a parabolic subgroup, 𝔤 and 𝔭 their Lie algebras. We prove a microlocal version of Gyoja's conjectures [2] about a relation between the irreducibility of generalized Verma modules on 𝔤 induced from 𝔭 and the zeroes of b-functions of P-semi-invariants on G. Our method uses a duality for twisted 𝒟-modules on generalized flag manifolds.

Soient G un groupe algébrique sur connexe semi-simple, P un sous-groupe parabolique, 𝔤 et 𝔭 leurs algèbres de Lie. On démontre une version microlocale des conjectures de Gyoja [2] sur une relation entre l'irreductibilité des modules de Verma généralisés sur 𝔤 induits de 𝔭 et les zéros des b-fonctions des quasi-invariants sur G par rapport à P. Notre méthode utilise une dualité pour les 𝒟-modules tordus sur les variétés de drapeaux généralisées.
