摘要

在本文中，我们发展了von Neumann代数上的双模理论，重点讨论了范畴方面。阐明了可偶性与有限指数之间的关系。我们还证明了对于具有有限维中心的von Neumann代数，Haagerup l2空间和cones融合对于有限指标的同态是泛函的。在此过程中，我们描述了不一定是双线性的双模之间映射的字符串图符号。

Dualizability and index of subfactors

In this paper, we develop the theory of bimodules over von Neumann algebras, with an emphasis on categorical aspects. We clarify the relationship between dualizability and finite index. We also show that, for von Neumann algebras with finite dimensional centers, the Haagerup L 2 -space and Connes fusion are functorial with respect to homor- phisms of finite index. Along the way, we describe a string diagram notation for maps between bimodules that are not necessarily bilinear.
