Constructing the quantum queer supergroup using Hecke-Clifford
superalgebras
In [DGLW], we use certain special elements and their commutation relations in the Hecke-Clifford algebras $H^c_{r,R}$ to derive some fundamental multiplication formulas associated with the natural bases in queer $q$-Schur superalgebras $Q_q(n,r;R)$ introduced in [DW2]. Here a natural basis element is defined by a special element $T_{A^{\star}}$ in $H^c_{r,R}$ associated …
