Connes’ bicentralizer problem and uniqueness of the injective factor of type $$III_ 1$$. (English) Zbl 0628.46061
This paper completes the classification of injective factors, cf. A. Connes [Ann. Math., II. Ser. 104, 73-115 (1976; Zbl 0343.46042) and J. Oper. Theory 14, 189-211 (1985; Zbl 0597.46063)]. The author proves that any hyperfinite factor of type $$III_ 1$$ has a trivial bicentralizer, and is, therefore isomorphic to the Araki-Woods factor $$R_{\infty}$$. He also gives a characterization of $$III_ 1$$-factors with only trivial bicentralizers.
