$\imath$ Schur超代数的乘法公式和同构定理

Multiplication formulas and isomorphism theorem of $\imath$Schur superalgebras

Jian Chen, Li Luo

摘要:

引入了$\imath$ Schur超代数的概念,它可以看作是Hecke代数上某些符号$q$ -置换模的中心化子代数(A型)的$q$ -Schur超代数的B/C型对应.给出了$\imath$ Schur超代数的一些乘法公式,并构造了它们的标准基.此外,我们建立了A型$q$-Schur超代数与$\imath$-Schur超代数之间的同构定理,从而得到了$\imath$-Schur超代数的半单性准则.

英文摘要:

We introduce the notion of $\imath$Schur superalgebra, which can be regarded as a type B/C counterpart of the $q$-Schur superalgebra (of type A) formulated as centralizer algebras of certain signed $q$-permutation modules over Hecke algebras. Some multiplication formulas for $\imath$Schur superalgebra are obtained to construct their canonical bases. Furthermore, we established an isomorphism theorem between the $\imath$Scuhr superalgebras and the $q$-Schur superalgebras of type A, which helps us derive a semisimplicity criteria of the $\imath$Schur superalgebras.
