报告内容简介:
This report summarizes the Beilinson--Lusztig--MacPherson (BLM) theory and its generalizations. BLM gave a geometric construction of quantum $\mathfrak{gl}_n$ via $q$-Schur algebras, and simultaneously constructed the canonical bases for the modified quantum group $\dot{U}_v(\mathfrak{gl}_n)$ within this geometric framework. This approach also yields the integral quantum Schur--Weyl duality. Subsequently, the theory was extended to affine quantum $\mathfrak{gl}_n$ as well as to super and $i$-quantum group analogues.
