Unipotent quantum coordinate ring and cominuscule prefundamental representations

Il-Seung Jang, Jae-Hoon Kwon, Euiyong Park

We continue the study of realization of the prefundamental modules $L_{r,a}^{\pm }$, introduced by Hernandez and Jimbo, in terms of unipotent quantum coordinate rings as in [J-Kwon-…
