摘要：The classical theory of symmetric pairs concerns involutions on Lie algebras. For each symmetric pair, there is a relative root system and a relative Weyl group. Quantum symmetric pairs are quantizations of classical symmetric pairs and i-quantum groups are certain quantum algebras arising from quantum symmetric pairs. In this talk, I will review relative Weyl groups and talk about our construction of relative braid group actions on i-quantum groups. This is joint with Weiqiang Wang.
