Brundan和Kleshchev证明了当量子参数q$是一个本原$(2l+1)$-th单位根时,仿射Hecke-Clifford超代数及其有限维“分圆”子的表示理论的某些部分受$A^{(2)}_{2l}$型李理论的控制。本文通过用$D^{(2)}_{l}$型李理论代替$A^{(2)}_{2l}$型李理论,证明了当$q$是$4l$次本原单位根时,类似的定理也成立。
Brundan and Kleshchev showed that some parts of the representation theory of the affine Hecke-Clifford superalgebras and its finite-dimensional "cyclotomic" quotients are controlled by the Lie theory of type $A^{(2)}_{2l}$ when the quantum parameter $q$ is a primitive $(2l+1)$-th root of unity. We show in this paper that similar theorems hold when $q$ is a primitive $4l$-th root of unity by replacing the Lie theory of type $A^{(2)}_{2l}$ with that of type $D^{(2)}_{l}$.
