报告简介：
A quantum symmetric pair consists of a quantum group U and its coideal subalgebra Ui. The Hall algebra constructions of U and Ui are given by Bridgeland and Lu-Wang, respectively. In this paper, we construct a Hall algebra framework for the coideal subalgebra structure of Ui in U, and for the quantum symmetric pair (U,Ui). As an application, we prove that the natural embedding of Ui in U, and the coproduct preserve the integral forms of Ui and U, which are used to construct the dual canonical bases. This is based on joint works with Weiqiang Wang and Zhuoyi Zhao.
