Applying a general categorical construction for the extension of dualities, we present a new proof of the Fedorchuk duality between the category of compact Hausdorff spaces with their quasi-open mappings and the category of complete normal contact algebras with suprema-preserving Boolean homomorphisms which reflect the contact relation.

二元性的扩展和 Fedorchuk 二元性的新方法

应用一般分类构造来扩展对偶性，我们提出了具有准开映射的紧 Hausdorff 空间的范畴与具有 suprema 保留布尔同态的完全正规接触代数的范畴之间的 Fedorchuk 对偶性的新证明。联系关系。
