Representations of quantum symmetric pairs at roots of unity

Jinfeng Song, Weinan Zhang

Let $θ$ be an involution of a complex semisimple Lie algebra $g$ and $(U_{v}, U_{v}^{})$ be the associated quantum symmetric pair at an odd root of unit…

Braid group action and quasi-split affine iquantum groups III

Ming Lu, Xiaolong Pan, Weiqiang Wang +1

This is the last of three papers on Drinfeld presentations of quasi-split affine iquantum groups $U^{}$ , settling the remaining type $AIII_{2 r}^{(τ)}$ …

Relative braid group symmetries on modified iquantum groups and their modules

Weiqiang Wang, Weinan Zhang

We present a comprehensive generalization of Lusztig's braid group symmetries for quasi-split iquantum groups. Specifically, we give 3 explicit rank one formulas for symmetries act…
