摘要

在单结论超序演算的框架下,定义了正则哥德尔系统的概念。一个相应的一般(不确定的)哥德尔值语义,以及一个(不确定的)线性直觉的Kripke-frames语义。我们证明了每一个正则哥德尔系统都归纳出一类哥德尔赋值(和Kripke框架),对于这些赋值它是强健全和完备的。该语义用于识别具有(强)切容许性的规范系统,并为这些系统提供决策过程。本文的结果,在证明理论和语义上,刻画了一个可以添加到命题哥德尔逻辑的(非确定性)连接词族。

Non-deterministic Connectives in Propositional Godel Logic
We define the notion of a canonical Godel system in the framework of single-conclusion hypersequent calculi. A corresponding general (nondeterministic) Godel valuation semantics is developed, as well as a (non-deterministic) linear intuitionistic Kripke-frames semantics. We show that every canonical Godel system induces a class of Godel valuations (and of Kripke frames) for which it is strongly sound and complete. The semantics is used to identify the canonical systems that enjoy (strong) cut-admissibility, and to provide a decision procedure for these systems. The results of this paper characterize, both proof-theoretically and semantically, a large family of (non-deterministic) connectives that can be added to propositional Godel logic.
