直觉量词的时间解释:一元情形

Temporal interpretation of intuitionistic quantifiers: Monadic case

Guram Bezhanishvili, Luca Carai

摘要:

在最近的一篇论文中,我们证明了直觉量词允许以下时间解释:“总是在未来”(对于$\forall$)和“过去的某个时候”(对于$\exists$)。本文研究直觉谓词逻辑的一元片断$\sf MIPC$的这种解释。众所周知,$\sf MIPC$被完全忠实地翻译成谓词$\sf S4$的一元片段$\sf MS4$(哥德尔翻译)。我们引入了一个新的时态扩展$\sf S4$,表示为$\sf TS4$,并提供了一个替代的完整和忠实的翻译$\sf MIPC$到$\sf TS4$,这产生了时间的解释一元直觉量词上面提到的。我们比较了这个新的翻译哥德尔翻译的$\sf MS4$和$\sf TS4$可以完全和忠实地翻译成一个时态扩展的$\sf MS4$,我们表示为$\sf MS4.t$。这是通过利用代数和关系语义的新逻辑介绍。作为一个副产品,我们证明了有限模型属性(FMP)的$\sf MS4.t$,并表明,FMP涉及的其他逻辑可以推导出作为一个结果的丰满和忠实的翻译考虑。

英文摘要:

In a recent paper we showed that intuitionistic quantifiers admit the following temporal interpretation: "always in the future" (for $\forall$) and "sometime in the past" (for $\exists$). In this paper we study this interpretation for the monadic fragment $\sf MIPC$ of the intuitionistic predicate logic. It is well known that $\sf MIPC$ is translated fully and faithfully into the monadic fragment $\sf MS4$ of the predicate $\sf S4$ (Gödel translation). We introduce a new tense extension of $\sf S4$, denoted by $\sf TS4$, and provide an alternative full and faithful translation of $\sf MIPC$ into $\sf TS4$, which yields the temporal interpretation of monadic intuitionistic quantifiers mentioned above. We compare this new translation with the Gödel translation by showing that both $\sf MS4$ and $\sf TS4$ can be translated fully and faithfully into a tense extension of $\sf MS4$, which we denote by $\sf MS4.t$. This is done by utilizing the algebraic and relational semantics for the new logics introduced. As a byproduct, we prove the finite model property (fmp) for $\sf MS4.t$ and show that the fmp for the other logics involved can be derived as a consequence of the fullness and faithfulness of the translations considered.
