Let $G$ be a second countable locally compact Hausdorff topological group and $P$ be a closed subsemigroup of $G$ containing the identity element $e\in G$ . Assume that the interior of $P$ is dense in $P$ . Let $\unicode[STIX]{x1D6FC}=\{{\unicode[STIX]{x1D6FC}_{x}\}}_{x\in P}$ be a semigroup of unital normal $\ast$ -endomorphisms of a von Neumann algebra $M$ with separable predual satisfying a natural measurability hypothesis. We show that $\unicode[STIX]{x1D6FC}$ is an $E_{0}$ -semigroup over $P$ on $M$ .

可测量的半群是连续的
让$G$ 是第二个可数局部紧致 Hausdorff 拓扑群,并且$P$ 是一个封闭的子半群$G$ 包含标识元素$e\in G$ . 假设内部$P$ 密集在$P$ . 让$\unicode[STIX]{x1D6FC}=\{{\unicode[STIX]{x1D6FC}_{x}\}}_{x\in P}$ 是单位正态的半群$\ast$ -冯诺依曼代数的自同态$M$ 具有满足自然可测性假设的可分离预对偶。我们表明$\unicode[STIX]{x1D6FC}$ 是一个$E_{0}$ -半组结束$P$ 在$M$ .
