In this paper, we extend Ocneanu’s theory of connections on graphs to define a 2-category whose 0-cells are tracial Bratteli diagrams, and whose 1-cells are generalizations of unitary connections. We show that this 2-category admits an embedding into the 2-category of hyperfinite von Neumann algebras, generalizing fundamental results from subfactor theory to a 2-categorical setting.

Bratteli 图上的酉连接
在本文中,我们扩展了 Ocneanu 的图连接理论,定义了一个 2-范畴,其 0-单元是tracial Bratteli 图,其 1-单元是酉连接的推广。我们证明这个 2 类别允许嵌入到超有限冯诺依曼代数的 2 类别中,将子因子理论的基本结果推广到 2 类别设置。
