限定摹状词与混合时态逻辑

Definite Descriptions and Hybrid Tense Logic

Andrzej Indrzejczak, Michał Zawidzki

AI总结:

本文构建了以谓词抽象和限定摹状词为唯一非严格词项的一阶混合时态逻辑,用处理 sat-公式的表推演演算形式化,并构造性证明插值定理,扩展了 Blackburn 与 Marx 的结果。

摘要:

我们提出了一个一阶混合时态逻辑版本,其中谓词抽象和限定摹状词是唯一的非严格词项。该逻辑通过一种处理 sat-公式的表推演演算加以形式化。这里采用的特定 DD 理论本质上基于 Russell 的进路,但将摹状词视为真正的词项。然而,Russell 式进路的还原论方面以若干方式得到保留。此外,本文还形式化地发展了一种特殊形式的时态限定摹状词。文中给出了该演算的插值定理的构造性证明,这是对 Blackburn 和 Marx 所提供结果的扩展。

英文摘要:

We provide a version of first-order hybrid tense logic with predicate abstracts and definite descriptions as the only non-rigid terms. It is formalised by means of a tableau calculus working on sat-formulas. A particular theory of DD exploited here is essentially based on the approach of Russell, but with descriptions treated as genuine terms. However, the reductionist aspect of the Russellian approach is retained in several ways. Moreover, a special form of tense definite descriptions is formally developed. A constructive proof of the interpolation theorem for this calculus is given, which is an extension of the result provided by Blackburn and Marx.
