一句话:澄清原文健全性陈述中的隐含假设,并修正其完备性证明中的缺陷。
本文是对发表于 POPL 2023 的论文《Unrealizability Logic》的更正。原文在陈述健全性(soundness)时隐含了一个未明确说明的假设,并且其完备性(completeness)证明存在一个缺陷。作者在 Shaan Nagy 的协助下发现了这两个问题。本更正澄清了健全性陈述中所做的假设,使该假设显式化,并修正了完备性证明中的错误。通过这一更正,原文的健全性与完备性结果得以在更严谨的基础上成立。该更正不改变原文的核心逻辑框架,仅对证明细节和前提条件进行必要的补充与修正。
This is a corrigendum for the article "Unrealizability Logic" by Jinwoo Kim, Loris D’Antoni, and Thomas Reps, published in Proc. ACM Program. Lang. 7, POPL, Article 23 (January 2023), https://doi.org/10.1145/3571216. The authors, with the help of Shaan Nagy, discovered that there was an implicitly made assumption when stating soundness, and a flaw in the completeness proof of the original paper. This corrigendum clarifies the assumption made in the soundness statement and rectifies the completeness proof.
