协方差系统
Covariance systems
摘要:
我们引入新的定义的状态和协方差系统的表示。GNS构造被推广到这种情况。它将表示与协方差系统的每个状态相关联。接下来,状态被扩展到适当的协方差代数的状态。给出了两个应用程序。我们描述了一个非相对论性的量子粒子,我们给出了一个简单的描述量子时空模型介绍了多普利彻等人。
英文摘要:
We introduce new definitions of states and of representations of covariance systems. The GNS-construction is generalized to this context. It associates a representation with each state of the covariance system. Next, states are extended to states of an appropriate covariance algebra. Two applications are given. We describe a nonrelativistic quantum particle, and we give a simple description of the quantum spacetime model introduced by Doplicher et al.
