报告内容: In this talk, we introduce the affine q-web and Schur categories of type A, along with their cyclotomic quotients. These categories provide the first diagrammatic presentations for a broad class of algebras, including affine q-Schur algebras, higher-level affine Schur algebras, and cyclotomic q-Schur algebras. Furthermore, these categories (and their module categories) will serve as a natural framework for the categorification of the negative half of quantum affine gl_n and its integrable highest weight modules. This is joint work with Yaolong Shen and Weiqiang Wang.
