证明论语义与策略证明

Proof-theoretic Semantics and Tactical Proof

Alexander V. Gheorghiu, David J. Pym

摘要:

逻辑系统在解决问题中的应用可能是多种多样的,就像在证明数学定理或弄清楚如何与朋友见面一样。在任何一种情况下,问题解决活动都是通过搜索\emph{argument}来捕获的,\emph{argument}广泛地被认为是问题解决方案的证书。至关重要的是,要使这样的证书成为解决方案,它必须是\emph{valid},使其有效的是,它们是根据底层逻辑系统的推理概念良好构造的。我们提供了一个通用的框架,统一描述使用逻辑作为数学推理在上述意义上。我们使用Dummett-Prawitz传统中的证明理论有效性来定义论点的有效性,并使用策略证明理论来联系论点,推理和搜索。

英文摘要:

The use of logical systems for problem-solving may be as diverse as in proving theorems in mathematics or in figuring out how to meet up with a friend. In either case, the problem solving activity is captured by the search for an \emph{argument}, broadly conceived as a certificate for a solution to the problem. Crucially, for such a certificate to be a solution, it has be \emph{valid}, and what makes it valid is that they are well-constructed according to a notion of inference for the underlying logical system. We provide a general framework uniformly describing the use of logic as a mathematics of reasoning in the above sense. We use proof-theoretic validity in the Dummett-Prawitz tradition to define validity of arguments, and use the theory of tactical proof to relate arguments, inference, and search.
