Abstract
In this talk, we introduce (G,q)-opers to construct Bethe Ansatz equations for the open quantum spin chain. The correspondence provides examples of q-geometric Langlands correspondence. For open spin chains, we introduce a notion of reflection-invariant q-opers and a ame-singularity condition to q-connections. This work is based on 2512.23174 with Peter Koroteev and Rahul Singh.
