Non-commutativity of the central sequence algebra for separable non-type I C${}^{\ast }$-algebras

Hiroshi Ando, Eberhard Kirchberg

We show that if $A$ is a separable, simple and non-type I C${}^{\ast }$ algebra, then for every properly infinite hyperfinite von Neumann algebra $M$ with separable predual, its Ocnea…
