正则Monoidal语言

Regular Monoidal Languages

Matthew Earnshaw, Paweł Sobociński

摘要:

我们介绍了自由monoidal范畴中态射的正则语言,以及它们的相关文法和自动机。这些方法颠覆了关于词和树的正则语言的经典理论,而且还在字符串图上开辟了更广泛的语言类别。利用Monoidal和Carnival限制范畴的代数来研究正则Monoidal语言的性质,并给出了确定Monoidal自动机可识别正则Monoidal语言的充分条件.

英文摘要:

We introduce regular languages of morphisms in free monoidal categories, with their associated grammars and automata. These subsume the classical theory of regular languages of words and trees, but also open up a much wider class of languages over string diagrams. We use the algebra of monoidal and cartesian restriction categories to investigate the properties of regular monoidal languages, and provide sufficient conditions for their recognizability by deterministic monoidal automata.
