直觉主义分层图逻辑:语义与证明论

Intuitionistic Layered Graph Logic: Semantics and Proof Theory

Simon Docherty, David Pym

AI总结:

该文提出直觉主义分层图逻辑ILGL,给出其语义与证明论,证明可判定性及Stone对偶,并扩展至谓词版本,用于建模复杂系统的分层结构。

摘要:

复杂系统的模型广泛应用于物理和社会科学中,而分层概念通常建立在图论结构之上,是一种常见特征。我们描述了一种称为ILGL的直觉主义子结构逻辑,它给出了分层的解释。该逻辑是一个束系统,结合了通常的直觉主义连接词,以及一个非交换、非结合的合取(用于捕获分层)及其相关蕴含。我们给出了一个带标签的tableaux系统相对于图上的Kripke语义的可靠性和完备性定理。然后我们给出一个等价的关系语义,并通过表示定理证明其等价于代数语义。我们以两种方式利用这一结果。首先,我们通过证明代数语义具有有限可嵌入性来证明该逻辑的可判定性。其次,我们为该逻辑证明了一个Stone型对偶定理。通过引入ILGL超 doctrines 和索引分层框架的概念,我们能够将此结果扩展到该逻辑的谓词版本,并为分层图语义的扩展证明可靠性和完备性定理。我们用一个资源标记的bigraph模型来指示谓词ILGL的实用性。

英文摘要:

Models of complex systems are widely used in the physical and social sciences, and the concept of layering, typically building upon graph-theoretic structure, is a common feature. We describe an intuitionistic substructural logic called ILGL that gives an account of layering. The logic is a bunched system, combining the usual intuitionistic connectives, together with a non-commutative, non-associative conjunction (used to capture layering) and its associated implications. We give soundness and completeness theorems for a labelled tableaux system with respect to a Kripke semantics on graphs. We then give an equivalent relational semantics, itself proven equivalent to an algebraic semantics via a representation theorem. We utilise this result in two ways. First, we prove decidability of the logic by showing the finite embeddability property holds for the algebraic semantics. Second, we prove a Stone-type duality theorem for the logic. By introducing the notions of ILGL hyperdoctrine and indexed layered frame we are able to extend this result to a predicate version of the logic and prove soundness and completeness theorems for an extension of the layered graph semantics . We indicate the utility of predicate ILGL with a resource-labelled bigraph model.
