Perfectness of Kirillov--Reshetikhin crystals for nonexceptional types

Ghislain Fourier, Masato Okado, Anne Schilling

Abstract

For nonexceptional types, we prove a conjecture of Hatayama et al. about the prefectness of Kirillov--Reshetikhin crystals.
Résumé. Pour les types non-exceptionnels, on démontre une conjecture de Hatayama et al. concernant la perfection des cristaux de Kirillov--Reshetikhin.
