Every sum system is divisible
Masaki Izumi
We show that every sum system is divisible. Combined with B. V. R. Bhat and R. Srinivasan's result, this shows that every product system arising from a sum system (and every genera…
Classification of Noncommuting Quadrilaterals of Factors
Pinhas Grossman, Masaki Izumi
A quadrilateral of factors is an irreducible inclusion of factors with intermediate subfactors and such that and generate and the intersection of…
A perturbation problem for the shift semigroup
Masaki Izumi
Motivated by B. Tsirelson's construction of -semigroups of type III, we investigate a -semigroup acting on the space of square integrable functions of the half line whose…
Canonical extension of endomorphisms of type III factors
Masaki Izumi
We extend the notion of the canonical extension of automorphisms of type III factors to the case of endomorphisms with finite statistical dimensions. Following the automorphism cas…
