Stone对偶在零维T2空间范畴上的两个推广

Two extensions of the Stone Duality to the category of zero-dimensional Hausdorff spaces

Georgi Dimov, Elza Ivanova-Dimova

摘要:

推广Stone对偶定理,证明了零维T2空间和连续映射范畴ZHaus的两个对偶定理.这两个结果都很容易地导出了Tarski对偶定理,以及关于极端不连通的Tychonoff空间和连续映射范畴EDTych的两个新的对偶定理。另外,我们还刻画了零维T2空间的零维Hausdorff紧化范畴ZComp的对偶等价范畴,并作为推论得到了零维T2空间的零维紧化的Dwinger定理.

英文摘要:

Extending the Stone Duality Theorem, we prove two duality theorems for the category ZHaus of zero-dimensional Hausdorff spaces and continuous maps. Both of them imply easily the Tarski Duality Theorem, as well as two new duality theorems for the category EDTych of extremally disconnected Tychonoff spaces and continuous maps. Also, we describe two categories which are dually equivalent to the category ZComp of zero-dimensional Hausdorff compactifications of zero-dimensional Hausdorff spaces and obtain as a corollary the Dwinger Theorem about zero-dimensional compactifications of a zero-dimensional Hausdorff space.
