As an application, we can show the existence of subfactors with principal graph D_{2n} without full use of Ocneanu's paragroup theory.. |

The first one is an action whose modular part is normal. We will construct a new invariant which generalizes a characteristic invariant for a discrete group action, and we will present a complete classification. The second is a centrally free action. By constructing a Rohlin tower in an asymptotic centralizer, we will show that the Connes–Takesaki module is a complete invariant.. |

This result provides alternative approaches to some preceding results such as Kawahigashi’s classification of flows on the injective type II1 factor, the classification of injective type III factors due to Connes, Krieger and Haagerup and the non-fullness of type III0 factors. Several concrete examples are also studied.. |
