集束蕴涵逻辑中的聚焦证明搜索

Focused Proof-search in the Logic of Bunched Implications

Alexander Gheorghiu, Sonia Marin

摘要:

集束蕴涵(BI)逻辑自由地组合了加法和乘法连接词,包括蕴涵;然而,尽管其证明理论得到了充分的研究,但BI中的证明搜索一直是一个难题。聚焦原则是对证明-搜索空间的一种限制,它可以捕获各种目标导向的证明-搜索过程。在本文中,我们表明,集中的证明搜索是完整的BI首先重新制定传统的束的嵌套序列,使用更简单的数据结构,然后与极化和集中的变体,我们显示是健全的和完整的,通过削减消除参数。这建立了一个操作语义集中证明搜索的逻辑集束的影响。

英文摘要:

The logic of Bunched Implications (BI) freely combines additive and multiplicative connectives, including implications; however, despite its well-studied proof theory, proof-search in BI has always been a difficult problem. The focusing principle is a restriction of the proof-search space that can capture various goal-directed proof-search procedures. In this paper, we show that focused proof-search is complete for BI by first reformulating the traditional bunched sequent calculus using the simpler data-structure of nested sequents, following with a polarised and focused variant that we show is sound and complete via a cut-elimination argument. This establishes an operational semantics for focused proof-search in the logic of Bunched Implications.
