Quasinormalizers in crossed products of von Neumann algebras
Jon Bannon, Jan Cameron, Ionut Chifan +3
We study the relationship between the dynamics of the action of a discrete group on a von Neumann algebra , and structural properties of the associated crossed product i…
Structural properties of close II factors
Jan Cameron, Erik Christensen, Allan M. Sinclair +3
We show that a number of key structural properties transfer between sufficiently close II factors, including solidity, strong solidity, uniqueness of Cartan masas and property…
Type II_1 factors satisfying the spatial isomorphism conjecture
Jan Cameron, Erik Christensen, Allan M. Sinclair +3
This paper addresses a conjecture of Kadison and Kastler that a von Neumann algebra M on a Hilbert space H should be unitarily equivalent to each sufficiently close von Neumann alg…
Kadison-Kastler stable factors
Jan Cameron, Erik Christensen, Allan M. Sinclair +3
A conjecture of Kadison and Kastler from 1972 asks whether sufficiently close operator algebras in a natural uniform sense must be small unitary perturbations of one another. For $…
A remark on the similarity and perturbation problems
Jan Cameron, Erik Christensen, Allan M. Sinclair +3
In this note we show that Kadison's similarity problem for C*-algebras is equivalent to a problem in perturbation theory: must close C*-algebras have close commutants?
Groupoid normalizers of tensor products
Junsheng Fang, Roger R. Smith, Stuart A. White +1
We consider an inclusion of finite von Neumann algebras satisfying . A partial isometry is called a groupoid normalizer if $vBv^*, v^*B…
