SUBFACTORS OF INDEX LESS THAN 5, PART 4: VINES
SUBFACTORS OF INDEX LESS THAN 5, PART 4: VINES
We eliminate 39 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 …
