AI 中文摘要
S4 - 从属代数是闭包代数的推广。本文通过双拓扑空间⟨X,τ,τS⟩给出S4 - 从属代数的拓扑表示，其中⟨X,τ⟩是斯通空间，τS是能刻画从属关系的拓扑。应用此双拓扑表示刻画S5 - 从属代数和格从属关系。还表明与从属关系兼容的同余和斯通空间⟨X,τ⟩的某些闭子集（也是⟨X,τS⟩空间的饱和集）之间存在双射对应。此外，探索了S4 - 从属代数之间的两种态射，并为每种态射提供拓扑表示。
英文摘要
S4-subordination algebras are a generalization of the closure algebras. In this paper, we give a topological representation for S4-subordination algebras by means of bitopological spaces $\left<X,τ,τ_{S}\right>$, where $\left<X,τ\right>$ is a Stone space and $τ_{S}$ is a topology that enables the characterization of the subordination relation. We apply this bitopological representation to give a characterization of S5-subordination algebras and lattice subordinations. We also show that there exists a bijective correspondence between congruence compatible with the subordination and certain closed subsets of the Stone space $\left<X,τ\right>$ that are also saturated sets of the space $\left<X,τ_{S}\right>$. Additionally, we explore two types of morphisms between S4-subordination algebras: one based on Boolean homomorphisms and another based on meet-homomorphisms. Finally, we provide a topological representation for each type of morphism.
