Centers of q-Schur algebras
Jian Chen, Xirui Yu
We give a direct BLM-coordinate description of the centers of generic -Schur algebras for type and type . For the -Schur algebras o…

Three approaches to the Howe duality between quantum general linear supergroups
Li Luo, Xirui Yu, Zhongguo Zhou
The Howe duality between quantum general linear supergroups was firstly established by Y. Zhang via quantum coordinate superalgebras. In this paper, we provide two other approaches…

Affine quantum Schur algebras and quantum groups with three parameters
Li Luo, Xirui Yu
We study the affine quantum Schur algebras corresponding to the affine Hecke algebras of type C with three parameters. Multiplication formulas for semisimple generators are derived…
