紧量子群及其子因子的表示

Representations of compact quantum groups and subfactors

Teodor Banica

摘要:

我们将Popa系统(=子因子的标准不变量)与紧致量子群的有限维表示联系起来。我们用这种方式来描述系统:这些系统可以在有限维希尔伯特空间上"表示“。这是由一个普遍的结构证明的。我们显式计算(在一些自由积)的操作,从表示的紧凑量子群波帕系统,然后通过通用的建设。证明了紧量子群的协变性的Kesten型结果,这使我们能够将其与子因子的协变性进行比较。

英文摘要:

We associate Popa systems (= standard invariants of subfactors) to the finite dimensional representations of compact quantum groups. We characterise the systems arising in this way: these are the ones which can be ``represented'' on finite dimensional Hilbert spaces. This is proved by an universal construction. We explicitely compute (in terms of some free products) the operation of going from representations of compact quantum groups to Popa systems and then back via the universal construction. We prove a Kesten type result for the co-amenability of compact quantum groups, which allows us to compare it with the amenability of subfactors.
