Compatibility of Drinfeld presentations for split affine Kac-Moody quantum symmetric pairs

Tomasz Przezdziecki, Jian-Rong Li

Let $(\mathbf{U},{\mathbf{U}}^{ı})$ be a split affine quantum symmetric pair of type ${\mathsf{B}}_n^{(1)},{\mathsf{C}}_n^{(1)}$ or ${\mathsf{D}}_n^{(1)}$. We prove factorization and…
