Abstract:

  Bao-Kujawa-Li-Wang and Fan-Li gave the Schur-Weyl duality between the coideal algebra and Hecke algebra of type B/C/D by using convolution algebra of the equivariant function on the isotropic flag variety. Motivated by the their works and langlands reciprocity,we provide a geometric approach to these quantum coideal algebra of U_q(sl_n) via equivariant K-theory on the steinberg variety. This is a preliminary results joint work with Zhaobing Fan and Husileng Xiao.
