摘要
本文通过研究群似酉系统的若干重要性质,证明了作用在可分Hilbert空间上的任一群似酉系统都具有膨胀性.这一结果将韩德广与Larson关于群酉系统具有膨胀性的结果扩大到了群似酉系统.
In this paper, we study some important properties of the group-like unitary system acting on a separable Hilbert space and prove that it has the dilation property. So the result of the dilation property of the group unitary system given by Han and Larson is generalized to that of the group-like unitary system.
