基于交互学习的EM1实现Heyting算法

Interactive Learning-Based Realizability for Heyting Arithmetic with EM1

Federico Aschieri, Stefano Berardi

摘要:

我们将“有限近似”的思想应用于算术的语义,用于提供Herbrand定理的计算解释,并且我们将经典证明解释为在自然数语言和哥德尔系统$\SystemT$的映射的适当结构$\StructureN$上的构造性证明(具有$\vee, \exists$的构造性规则)。我们引入了一个新的可实现性语义,我们称之为“基于交互式学习的可实现性”,为海廷算术加$\EM_1$(排除中间公理限制到$Σ^0_1$公式)。$\StructureN$的个体随着时间的推移而进化,实现者可能通过影响他们的进化而与他们“互动”。我们在Avigad的不动点结果上建立我们的语义,但是相同的语义可以在经典算术的不同构造性解释上定义(Berardi和de' Liguoro使用延拓)。我们的可实现性概念扩展了直觉主义的可实现性,与它的区别仅在于原子的情况:我们将原子实现者解释为“学习代理”。

英文摘要:

We apply to the semantics of Arithmetic the idea of ``finite approximation'' used to provide computational interpretations of Herbrand's Theorem, and we interpret classical proofs as constructive proofs (with constructive rules for $\vee, \exists$) over a suitable structure $\StructureN$ for the language of natural numbers and maps of Gödel's system $\SystemT$. We introduce a new Realizability semantics we call ``Interactive learning-based Realizability'', for Heyting Arithmetic plus $\EM_1$ (Excluded middle axiom restricted to $Σ^0_1$ formulas). Individuals of $\StructureN$ evolve with time, and realizers may ``interact'' with them, by influencing their evolution. We build our semantics over Avigad's fixed point result, but the same semantics may be defined over different constructive interpretations of classical arithmetic (Berardi and de' Liguoro use continuations). Our notion of realizability extends intuitionistic realizability and differs from it only in the atomic case: we interpret atomic realizers as ``learning agents''.
