$C^*$-代数的群胚模型与 Gelfand 对偶

算子代数 2018-08-13 v7

摘要

我们构造了一大类群胚态射,我们称之为群胚的偏态射,它们诱导极大和极小群胚 CC^*-代数的 *-态射。我们证明了将群胚对应于其极大(极小)群胚 CC^*-代数,以及将偏态射对应于其诱导态射的关联是函子(两者均扩张了 Gelfand 函子)。我们展示了如何将群胚 CC^*-代数之间的许多 *-态射进行几何可视化。作为应用,我们构造了 Jiang-Su 代数 Z\mathcal{Z} 和 Razak-Jacelon 代数 W\mathcal{W} 的整个归纳系统的群胚模型。

备注

Based on lots of feedback, we decided to change the title. We also added the case of reduced (or minimal) groupoid $C^*$-algebras. Lastly, we added a subsection (subsection 4.4) which completes the Gelfand duality theorem for commutative $C^*$-algebras will all $*$-morphisms. We updated some of our proofs and gave lots of examples that did not exist in the previous versions
