Abstract:
Last week we looked at the Jones tower, the relative commutants, and the principal graph for some subfactors associated to finite groups. This week, we'll continue our analysis of the relative commutants and the principal. We will show how minimal projections in the relative commutants correspond to bimodules, and we'll discuss how we view the principal graph as the fusion graph associated to these bimodules, where fusion refers to Connes fusion of bimodules. We'll then compute a particular example of importance in the classification of subfactors at index 3+\sqrt{5}.
