Relative center construction for -graded C-tensor categories and Longo-Rehren inclusions

Toshihiko Masuda

Gelaki-Naidu-Nikshych and Turaev-Virelizier showed the existence of -braiding on the relative Drinfeld center of a -graded tensor category. We will explain this concept from…

Actions of discrete amenable groups into the normalizers of full groups of ergodic transformations

Toshihiko Masuda

We apply Evans-Kishimoto's intertwining argument to the classification of actions of discrete amenable groups into the normalizer of a full group of an ergodic transformation. Our…

Classification of outer actions of discrete amenable groupoids on injective factors

Toshihiko Masuda

We classify outer actions (or -kernels) of discrete amenable groupoids on injective factors. Our method based on unified approach for classification of discrete amenab…

On the relative bicentralizer flows and the relative flow of weights of inclusions of factors of type III

Toshihiko Masuda

We show the relative bicentralizer flow and the relative flow of weights are isomorphic for an inclusion of injective factors of type III with finite index, or an irreducible d…

Classification of Roberts actions of strongly amenable C^* tensor categories on the injective factor of type III_1

Toshihiko Masuda

In this paper, we generalize Izumi's result on uniqueness of realization of finite C-tensor categories in the endomorphism category of the injective factor of type II_1 for fin…

A simple sufficient condition for triviality of obstruction in the orbifold construction for subfactors

Toshihiko Masuda

We present a simple sufficient condition for triviality of obstruction in the orbifold construction. As an application, we can show the existence of subfactors with principal graph…
