只有方程的名义逻辑

Nominal Logic with Equations Only

Ranald Clouston

摘要:

许多形式系统,特别是在计算机科学中,可以通过断言“名称的新鲜度”的副条件调制的方程来捕获;这些可以用名义方程逻辑(NEL)进行推理。像大多数这类逻辑一样,NEL使用新鲜度的概念作为第一类逻辑连接符。然而,当试图将结果从标准等式逻辑转换为标称设置时,这可能变得不方便。本文提出了一种逻辑的证明规则,其唯一的连接词是方程,我们称之为名义方程逻辑(NEoL)。我们证明了NEoL和NEL一样具有表达能力。然后,我们给出了一个简单的描述平等的空NEoL理论,然后扩展该结果来描述新鲜度的空NEL理论。

英文摘要:

Many formal systems, particularly in computer science, may be captured by equations modulated by side conditions asserting the "freshness of names"; these can be reasoned about with Nominal Equational Logic (NEL). Like most logics of this sort NEL employs this notion of freshness as a first class logical connective. However, this can become inconvenient when attempting to translate results from standard equational logic to the nominal setting. This paper presents proof rules for a logic whose only connectives are equations, which we call Nominal Equation-only Logic (NEoL). We prove that NEoL is just as expressive as NEL. We then give a simple description of equality in the empty NEoL-theory, then extend that result to describe freshness in the empty NEL-theory.
