Jingbang Guo
We study the dual algebras of (discrete) Hopf algebroids. In particular, we understand comodules over a Hopf algebroid as (discrete) modules over its dual algebra.

Langlands branching rule for type B snake modules
Jingmin Guo, Jian-Rong Li, Keyu Wang
We prove that each snake module of the quantum Kac-Moody algebra of type admits a Langlands dual representation, as conjectured by Frenkel and Hernandez (Lett. Math. Ph…
