关于与Sp(N-1)\subset Sl(N)有关的模范畴

On module categories related to Sp(N-1) \subset Sl(N)

Hans Wenzl

摘要:

设$V=\C^N$与$N$为奇数。我们构造了一个包含$\End_{U_q\sl_N}(V^{\otimes n})$的$\End_{Sp(N-1)}(V^{\otimes n})$的$q$ -变形.它是抽象二元代数的商,该代数是通过向Hecke代数$H_n$的生成元再添加一个生成元来定义的。这些结果表明$Rep(U_q\sl_N)$的模范畴的存在性,这些模范畴可能不是来自$U_q\sl_N$的已知的共理想子代数。此外,我们表明如何可以用来构建模块类别的相关融合张量类别以及子因子,沿着以前的工作的夹杂物$Sp(N)\subset SL(N)$。

英文摘要:

Let $V=\C^N$ with $N$ odd. We construct a $q$-deformation of $\End_{Sp(N-1)}(V^{\otimes n})$ which contains $\End_{U_q\sl_N}(V^{\otimes n})$. It is a quotient of an abstract two-variable algebra which is defined by adding one more generator to the generators of the Hecke algebras $H_n$. These results suggest the existence of module categories of $Rep(U_q\sl_N)$ which may not come from already known coideal subalgebras of $U_q\sl_N$. We moreover indicate how this can be used to construct module categories of the associated fusion tensor categories as well as subfactors, along the lines of previous work for inclusions $Sp(N)\subset SL(N)$.
