W. Arveson给出了将Hilbert空间的连续张量积系统与I型因子的自同态半群联系起来的一种方法。对于一般量子动力学半群,我们通过一个膨胀过程做同样的处理。由此得到的积系是原始半群的指标,其维数是原始半群的数值不变量。
W. Arveson showed a way of associating continuous tensor product systems of Hilbert spaces with endomorphism semigroups of type I factors. We do the same for general quantum dynamical semigroups through a dilation procedure. The product system so obtained is the index and its dimension is a numerical invariant for the original semigroup.
