Toward the classification of strongly self-absorbing -dynamical systems of compact groups

Masaki Izumi, Keiya Ohara

Strongly self-absorbing -algebras play a distinguished role in the classification of nuclear -algebras. Their dynamical analogues were introduced and ex…

Group-subgroup subfactors revisited

Masaki Izumi

For all Frobenius groups and a large class of finite multiply transitive permutation groups, we show that the corresponding group-subgroup subfactors are completely characterized b…

Graded extensions of generalized Haagerup categories

Pinhas Grossman, Masaki Izumi, Noah Snyder

We classify certain -graded extensions of generalized Haagerup categories in terms of numerical invariants satisfying polynomial equations. In particular, we constru…

Infinite families of potential modular data related to quadratic categories

Pinhas Grossman, Masaki Izumi

We present several infinite families of potential modular data motivated by examples of Drinfeld centers of quadratic categories. In each case, the input is a pair of involutive me…

Poly- group actions on Kirchberg algebras II

Masaki Izumi, Hiroki Matui

This is the second part of our serial work on the classification of poly- group actions on Kirchberg algebras. Based on technical results obtained in our previous work,…

The group structure of the homotopy set whose target is the automorphism group of the Cuntz algebra

Masaki Izumi, Taro Sogabe

We determine the group structure of the homotopy set whose target is the automorphism group of the Cuntz algebra for finite n in terms of K-theory. We show that there is…
