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…

Quasicentral modulus and self-similar sets: a supplementary result to Voiculescu's work

Kozo Ikeda, Masaki Izumi

In his recent work, Voiculescu generalized his remarkable formula for the quasicentral modulus of a commuting -tuple of hermitian operators with respect to the -Lorentz i…

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…

Classification of -quadratic unitary fusion categories

Cain Edie-Michell, Masaki Izumi, David Penneys

A unitary fusion category is called -quadratic if it has a group of invertible objects and one other orbit of simple objects under…

Algebraic realization of noncommutative near-group fusion categories

Masaki Izumi, Henry Tucker

Noncommutative near-group fusion categories were completely classified in the previous work of the first named author by using an operator algebraic method (and hence under the ass…
