S^1上C ~*-代数网的表示

Representations of nets of C*-algebras over S^1

Giuseppe Ruzzi, Ezio Vasselli

摘要:

最近,一种新的表示被用来描述弯曲时空上可观测网络的超选择扇区,并考虑了时空基本群的影响。利用这个表示的概念,我们证明了S^1上的C*-代数的任何网都允许忠实表示,并且当该网在Diff(S^1)下协变时,它允许在Diff(S^1)的任何顺从子群下协变的表示。

英文摘要:

In recent times a new kind of representations has been used to describe superselection sectors of the observable net over a curved spacetime, taking into account of the effects of the fundamental group of the spacetime. Using this notion of representation, we prove that any net of C*-algebras over S^1 admits faithful representations, and when the net is covariant under Diff(S^1), it admits representations covariant under any amenable subgroup of Diff(S^1).
