$3^n$子因子的分类及相关融合类别

The classification of $3^n$ subfactors and related fusion categories

Masaki Izumi

摘要:

我们研究了一系列(潜在的无限)子因子,称为$3^n$子因子,包括$A_4$,$A_7$和Haagerup子因子作为对应于$n=1,2,3$的前三个成员。推广了我们以前对奇数$n$的工作,我们进一步发展了一个Cuntz代数方法来构造$3^n$子因子,并表明在一个温和的假设下,$3^n$子因子和相关融合类别的分类被简化为显式多项式方程,这对奇数$n$自动成立。特别地,我们的方法与$n=4$给出了一个统一的构造4个有限深度子因子,直到对偶,没有索引$3+\sqrt{5}$的中间子因子。它也为格罗斯曼、斯奈德和作者重新构建Asaeda-Haagerup子因子提供了关键的一步。

英文摘要:

We investigate a (potentially infinite) series of subfactors, called $3^n$ subfactors, including $A_4$, $A_7$, and the Haagerup subfactor as the first three members corresponding to $n=1,2,3$. Generalizing our previous work for odd $n$, we further develop a Cuntz algebra method to construct $3^n$ subfactors and show that the classification of the $3^n$ subfactors and related fusion categories is reduced to explicit polynomial equations under a mild assumption, which automatically holds for odd $n$.In particular, our method with $n=4$ gives a uniform construction of 4 finite depth subfactors, up to dual,without intermediate subfactors of index $3+\sqrt{5}$. It also provides a key step for a new construction of the Asaeda-Haagerup subfactor due to Grossman, Snyder, and the author.
