谱距离:Moyal平面和非对易环面的结果

Spectral Distances: Results for Moyal Plane and Noncommutative Torus

Eric Cagnache, Jean-Christophe Wallet

摘要:

在最近提出的非紧谱三元组的框架下,考虑了非对易Moyal平面的谱距离,该三元组是非紧黎曼自旋流形的一种可能的非对易模拟.一个明确的公式之间的距离的任何两个元素的一个特定类别的纯态可以确定。并对相应结果进行了讨论。在无限远距离上存在纯态,表明态空间上谱距离的拓扑不是弱 * 拓扑。非对易环面的情况下,也被认为是一些状态之间的光谱距离的公式也得到了。

英文摘要:

The spectral distance for noncommutative Moyal planes is considered in the framework of a non compact spectral triple recently proposed as a possible noncommutative analog of non compact Riemannian spin manifold. An explicit formula for the distance between any two elements of a particular class of pure states can be determined. The corresponding result is discussed. The existence of some pure states at infinite distance signals that the topology of the spectral distance on the space of states is not the weak * topology. The case of the noncommutative torus is also considered and a formula for the spectral distance between some states is also obtained.
