报告摘要：We provide the geometric construction of a series of generalized Schur algebras of any type via Borel-Moore homologies and equivariant K-groups of generalized Steinberg varieties. As applications, we obtain a Schur algebra analogue of the local geometric Langlands correspondence of any type, provide an equivariant K-theoretic realization of quasi-split i-quantum groups of affine type AIII, and establish a geometric Howe duality for affine i-quantum groups. This is joint work with my students Zheming Xu and Yang Yang.
