算子代数 2020-04-20 v3

摘要

我们证明:当 M,N1,N2M,N_{1},N_{2} 为迹冯·诺依曼代数且 MMωM'\cap M^{\omega} 为交换时,M(MˉN1)ωM'\cap(M\bar{\otimes}N_{1})^{\omega}M(MˉN2)ωM'\cap(M\bar{\otimes}N_{2})^{\omega}(MˉN1ˉN2)ω(M\bar{\otimes}N_{1}\bar{\otimes}N_{2})^{\omega} 中交换。作为推论,我们获得了关于形如 MˉNM\bar{\otimes}NII1\rm{II}_{1} 因子的 McDuff 分解的信息,其中 MM 为非 McDuff 因子。
