Centers of quantum Schur superalgebras from Hecke algebras

Qiang Fu, Yingshan Luo, Chengquan Sun

We study the center of the quantum Schur superalgebra $S_{v} (m ∣ n, r)$ associated with the general linear Lie superalgebra $gl_{m ∣ n}$ . Using the super Schur--Weyl…

Quantum current algebra $U (gl_{n} [t])$ : canonical bases, rigidity, and relation with Yangians

Qiang Fu

We introduce a quantum deformation $U (gl_{n} [t])$ of the universal enveloping algebra of the current algebra $gl_{n} [t]$ , realized as a parabolic subalge…
