我们证明,if 是一个(不一定是单位的)可分离、简单且非 I 型 C 代数,那么对于每个具有可分离预置的适当无限超有限冯·诺依曼代数,其 Ocneanu 中心序列代数作为第二作者定义的中心序列代数的子商。特别是,这肯定地回答了 Kirchberg 的问题 [“C 代数和强纯无限代数中的中心序列”,算子代数:2004 年阿贝尔研讨会,第一届阿贝尔研讨会论文集,奥斯陆,2004 年 9 月 3-5 日(编辑 O. Bratteli、S. Neshveyev 和 C. Skau;Springer,柏林,海德堡, 2006), X, 279, 175–231]:约简自由群 C 代数非交换的中心序列 C 代数。
We show that ifis a (not necessarily unital) separable, simple and non-type I C-algebra, then for every properly infinite hyperfinite von Neumann algebrawith separable predual, its Ocneanu central sequence algebraarises as a sub-quotient of the central sequence algebradefined by the second-named author. In particular, this answers affirmatively the question of Kirchberg [‘Central sequences in C-algebras and strongly purely infinite algebras’,Operator algebras: the Abel Symposium 2004, Proceedings of the First Abel Symposium, Oslo, 3–5 September 2004 (eds O. Bratteli, S. Neshveyev and C. Skau; Springer, Berlin, Heidelberg, 2006), X, 279, 175–231]: the central sequence C-algebra of the reduced free group C-algebrais non-commutative.
