講演タイトル：Introduction to iQuantum Groups
日程：6/16（月）16:45--18:15
場所：理学部F棟F415（中講究室）
Abstract: iQuantum groups arising from quantum symmetric pairs can be
viewed as a vast generalization of Drinfeld-Jimbo quantum groups. Braid
group symmetries for quantum groups and their modules were formulated by
Lusztig and they have played an important role in understanding the finer
structures of quantum groups such as PBW and canonical bases. In the
setting of quasi-split iquantum groups, we shall construct the relative
braid group symmetries (associated with the relative Weyl group for
symmetric pairs), (1) providing explicit rank one formulas on integrable
modules in terms of iDivided powers, (2) connecting to Lusztig's braid
group symmetries via quasi Kmatrix. This is joint work with Weinan Zhang
(Hong Kong).
