中文摘要 |
最近,Dawson和Feinstein證明了一個交換的Banach代數的拓樸穩定秩是一的話,那它的 Banach 代數整擴張的拓樸穩定秩也是一。在這篇論文中,我們提供了這個命題的部分相反結果:如果一個交換的C*-代數的某個Arens-Hoffman擴張的拓樸穩定秩是一的話,那這個C*-代數的拓樸穩定秩也是一。 |
Abstract |
Recently, Dawson and Feinstein showed that a Banach algebra integral extension B of a commutative Banach algebra A of topological stable rank one is again of topological stable rank one. In this thesis, we provide a partial converse to this statement: If an Arens-Hoffman extension A® of a commutative C*-algebra A has topological stable rank one then A has topological stable rank one. |
