指数小于5的子因子,第4部分:葡萄树

Subfactors of index less than 5, part 4: vines

David Penneys, James E. Tener

摘要:

我们消除了38个无限家庭的可能的主图的一部分,分类的子因子指数5。Calegari-Morrison-Snyder的一个数论结果推广了Asaeda-Yasuda,将每个无限族减少到有限个情况。我们提供了算法计算的有效常数,这一结果所需的,我们得到28个可能的主图。Ostrik d数检验和代数整数检验将该列表减少到索引范围(4,5)中的7个图,这些图实际上作为主图出现。

英文摘要:

We eliminate 38 infinite families of possible principal graphs as part of the classification of subfactors up to index 5. A number-theoretic result of Calegari-Morrison-Snyder, generalizing Asaeda-Yasuda, reduces each infinite family to a finite number of cases. We provide algorithms for computing the effective constants that are required for this result, and we obtain 28 possible principal graphs. The Ostrik d-number test and an algebraic integer test reduce this list to 7 graphs in the index range (4,5) which actually occur as principal graphs.
