Stone对偶对斜布尔代数的一个加细

A refinement of Stone duality to skew Boolean algebras

Ganna Kudryavtseva

摘要:

本文建立了两个对偶定理,改进了广义布尔代数与局部紧布尔空间之间的经典Stone对偶。在第一个定理中,我们证明了态射是真斜布尔代数同态的左手斜布尔代数范畴等价于态射是连续真映射上的余同态的局部紧布尔空间上的余空间范畴.在第二个定理中,我们证明了态射是真斜布尔$\cap$-代数同态的左手斜布尔$\cap$ -代数范畴等价于态射是连续真映射上的内射代数空间上的局部紧布尔空间上的具有紧闭根均衡器的代数空间范畴.

英文摘要:

We establish two duality theorems which refine the classical Stone duality between generalized Boolean algebras and locally compact Boolean spaces. In the first theorem we prove that the category of left-handed skew Boolean algebras whose morphisms are proper skew Boolean algebra homomorphisms is equivalent to the category of étale spaces over locally compact Boolean spaces whose morphisms are étale space cohomomorphisms over continuous proper maps. In the second theorem we prove that the category of left-handed skew Boolean $\cap$-algebras whose morphisms are proper skew Boolean $\cap$-algebra homomorphisms is equivalent to the category of étale spaces with compact clopen equalizers over locally compact Boolean spaces whose morphisms are injective étale space cohomomorphisms over continuous proper maps.
