论文摘要
(PER)闭合空间是对离散结构中社区概念的拓扑空间的概括,广泛用于建模分布式系统的空间方面。 在本文中,我们介绍了一个抽象的理论框架,以系统地研究封闭空间的逻辑方面。为此,我们介绍了关闭(超级)学说的概念,即赋予通货膨胀运算符(并受到适当条件)的学说。这一概念的一般性和有效性是由许多例子,模糊集,代数结构,煤层自然产生的许多例子,并立即覆盖了Kripke框架和概率框架(即Markov Chains)。然后,我们展示了如何通过以路径的一般概念来解释有关包围性和可及性的空间逻辑构造。通过利用一般的分类结构,我们为封闭操作员的各种逻辑片段提供了公理化和声音和完整的语义。 因此,闭合高核心对于完善和改善现有空间逻辑的理论很有用,尤其是针对新应用的新空间逻辑的定义。
(Pre)closure spaces are a generalization of topological spaces covering also the notion of neighbourhood in discrete structures, widely used to model and reason about spatial aspects of distributed systems. In this paper we introduce an abstract theoretical framework for the systematic investigation of the logical aspects of closure spaces. To this end, we introduce the notion of closure (hyper)doctrines, i.e. doctrines endowed with inflationary operators (and subject to suitable conditions). The generality and effectiveness of this concept is witnessed by many examples arising naturally from topological spaces, fuzzy sets, algebraic structures, coalgebras, and covering at once also known cases such as Kripke frames and probabilistic frames (i.e., Markov chains). Then, we show how spatial logical constructs concerning surroundedness and reachability can be interpreted by endowing hyperdoctrines with a general notion of paths. By leveraging general categorical constructions, we provide axiomatisations and sound and complete semantics for various fragments of logics for closure operators. Therefore, closure hyperdoctrines are useful both for refining and improving the theory of existing spatial logics, but especially for the definition of new spatial logics for new applications.
