Ana de Almeida Borges

AI总结:

本研究在Coq证明助手中实现了单模态量化反思演算$\textsf{QRC}_1$的深度嵌入,完成可变论域Kripke模型与可靠性定理的形式化,梳理设计决策并给出简化的新证明。

摘要:

我们提出了单模态量化反思演算($\textsf{QRC}_1$)的Coq形式化。$\textsf{QRC}_1$是一种可判定的严格正量化模态逻辑,此前因其在证明论中的应用而被研究。研究亮点包括$\textsf{QRC}_1$在Coq证明助手中的深度嵌入、可变论域Kripke模型概念的机械化以及可靠性定理的形式化。我们聚焦于该形式化过程中固有的设计决策,以及催生全新简化证明的洞见。

英文摘要:

We present a Coq formalization of the Quantified Reflection Calculus with one modality, or $\mathsf{QRC}_1$. This is a decidable, strictly positive, and quantified modal logic previously studied for its applications in proof theory. The highlights are a deep embedding of $\mathsf{QRC}_1$ in the Coq proof assistant, a mechanization of the notion of Kripke model with varying domains and a formalization of the soundness theorem. We focus on the design decisions inherent to the formalization and the insights that led to new and simplified proofs.
