关于拟序图系统

On Quasi Ordinal Diagram Systems

Mitsuhiro Okada, Yuta Takahashi

摘要:

本文的目的有两个:首先,我们推广Okada-Takeuti的良好拟序图理论,利用最近的结果Dershowitz-Tzameret的版本的树嵌入定理与间隙条件。其次,我们讨论了可能使用这样的强序数符号系统的目的,一个典型的传统的终止证明方法长期重写系统,特别是二阶(基于模式匹配)重写系统,包括重写理论版本的布赫霍尔茨的九头蛇游戏。

英文摘要:

The purposes of this note are the following two; we first generalize Okada-Takeuti's well quasi ordinal diagram theory, utilizing the recent result of Dershowitz-Tzameret's version of tree embedding theorem with gap conditions. Second, we discuss possible use of such strong ordinal notation systems for the purpose of a typical traditional termination proof method for term rewriting systems, especially for second-order (pattern-matching-based) rewriting systems including a rewrite-theoretic version of Buchholz's hydra game.
