Title: Equivariant K-theory and quantum symmetric pairs
Speaker: Zhaobing Fan, Science College, Harbin Engineering University
Abstract: Bao-Kujawa-Li-Wang and Fan-Li provided the Schur-Weyl duality between the quantum coideal algebras and Hecke algebras of types B/C/D by using equivariant functions on the isotropic flag varieties. Motivated by their works and Langlands reciprocity, we provide a geometric approach to these quantum coideal algebras of U_q(sl_n) via equivariant K-theory on the steinberg varieties. This is a preliminary result joint with Haitao Ma and Husileng Xiao.
