Abstract

In this paper, by means of upper approximation operators in rough set theory, we study representations for sL-domains and its special subclasses. We introduce the concepts of sL-approximation spaces, L-approximation spaces and bc-approximation spaces, which are special types of CF-approximation spaces. We prove that the collection of CF-closed sets in an sL-approximation space (resp., an L-approximation space, a bc-approximation space) ordered by set-theoretic inclusion is an sL-domain (resp., an L-domain, a bc-domain); conversely, every sL-domain (resp., L-domain, bc-domain) is order-isomorphic to the collection of CF-closed sets of an sL-approximation space (resp., an L-approximation space, a bc-approximation space). Consequently, we establish an equivalence between the category of sL-domains (resp., L-domains) with Scott continuous mappings and that of sL-approximation spaces (resp., L-approximation spaces) with CF-approximable relations.
CF 近似空间何时捕获 sL 域
本文通过粗糙集理论中的上近似算子,研究 sL 域及其特殊子类的表示。我们引入了 sL 近似空间、L 近似空间和 bc 近似空间的概念,它们都是 CF 近似空间的特殊类型。我们证明,在 sL-approximation 空间(或者说,一个 L-approximation 空间,一个 bc-approximation 空间)中,通过集合论包容排序的 CF 闭集的集合是一个 sL 域(或者说、反过来,每个 sL 域(又称 L 域、bc 域)与 sL 近似空间(又称 L 近似空间、bc 近似空间)的 CF 闭集的集合是有序同构的。)因此,我们建立了具有斯科特连续映射的 sL-域(或 L-域)范畴与具有 CF-approximable 关系的 sL-approximation 空间(或 L-approximationspaces )范畴之间的等价性。
