轻逻辑与最优约简:完备性与复杂性

Light Logics and Optimal Reduction: Completeness and Complexity

Patrick Baillot, Paolo Coppola, Ugo Dal Lago

摘要:

初等和轻仿射逻辑中的非线性项的分类(分别为EAL,LAL)已经研究了两个不同的原因:一方面,使用LAL(EAL,resp.)证明网承认一个有保证的多项式(分别是初等的)另一方面,这些术语也可以通过使用Lamping算法的抽象版本的最优约简来评估。第一个约简是全局的,而第二个约简是局部的和异步的。我们证明,对于LAL(EAL,resp.)类型的条款,兰坪的抽象算法也承认一个多项式(小学,分别)。绑定我们还显示了它的健全性和完整性(EAL和LAL类型不动点),通过使用一个简单的几何交互模型(上下文语义)。

英文摘要:

Typing of lambda-terms in Elementary and Light Affine Logic (EAL, LAL, resp.) has been studied for two different reasons: on the one hand the evaluation of typed terms using LAL (EAL, resp.) proof-nets admits a guaranteed polynomial (elementary, resp.) bound; on the other hand these terms can also be evaluated by optimal reduction using the abstract version of Lamping's algorithm. The first reduction is global while the second one is local and asynchronous. We prove that for LAL (EAL, resp.) typed terms, Lamping's abstract algorithm also admits a polynomial (elementary, resp.) bound. We also show its soundness and completeness (for EAL and LAL with type fixpoints), by using a simple geometry of interaction model (context semantics).
