线性逻辑分层的抽象方法

An Abstract Approach to Stratification in Linear Logic

Pierre Boudes, Damiano Mazza, Lorenzo Tortora de Falco

摘要:

我们研究分层的概念,用于子系统的线性逻辑与低复杂性界限上的削减消除程序(所谓的轻逻辑),从抽象的角度来看,引入一个逻辑系统,其中分层是由一个单独的模态处理。这种模态是吉拉德的轻线性逻辑的段落模态的概括,它产生于一种适用于线性逻辑所有模型的一般范畴结构。因此,我们了解到,分层可以制定独立的指数模态;当它被迫连接到指数模态,它产生有趣的复杂性属性。特别是,从我们的分析干三个替代的重新制定的Baillot和Mazza的线性逻辑的水平:一个几何,一个互动,一个语义。

英文摘要:

We study the notion of stratification, as used in subsystems of linear logic with low complexity bounds on the cut-elimination procedure (the so-called light logics), from an abstract point of view, introducing a logical system in which stratification is handled by a separate modality. This modality, which is a generalization of the paragraph modality of Girard's light linear logic, arises from a general categorical construction applicable to all models of linear logic. We thus learn that stratification may be formulated independently of exponential modalities; when it is forced to be connected to exponential modalities, it yields interesting complexity properties. In particular, from our analysis stem three alternative reformulations of Baillot and Mazza's linear logic by levels: one geometric, one interactive, and one semantic.
