AI总结:

本文刻画了允许语言等价性判定的Pomset自动机片段,证明其与序列有理表达式对应,从而给出序列有理表达式等价性可判定的新证明。

摘要:

Pomset自动机是弱双Kleene代数的一种操作模型,该代数描述了可以将执行分叉为并行线程的程序,在这些线程完成后,执行可以汇合以恢复为单个线程。我们刻画了Pomset自动机的一个片段,该片段允许语言等价性的判定过程。此外,我们证明了这个片段恰好对应于序列有理表达式,即带有有界并行附加算子的有理表达式。因此,我们获得了序列有理表达式等价性可判定性的一个新证明。

英文摘要:

Pomset automata are an operational model of weak bi-Kleene algebra, which describes programs that can fork an execution into parallel threads, upon completion of which execution can join to resume as a single thread. We characterize a fragment of pomset automata that admits a decision procedure for language equivalence. Furthermore, we prove that this fragment corresponds precisely to series-rational expressions, i.e., rational expressions with an additional operator for bounded parallelism. As a consequence, we obtain a new proof that equivalence of series-rational expressions is decidable.
