Recently, reasoning with string diagrams has been implemented concretely via double-pushout (DPO) hypergraph rewriting. The hypergraph representation has the twin advantages of being convenient for mechanisation and of completely absorbing the structural laws of symmetric monoidal categories, leaving just the domain-specific equations explicit in the rewriting system. In many applications across different disciplines (linguistics, concurrency, quantum computation, control theory,...) the structural component appears to be richer than just the symmetric monoidal structure, as it includes one or more Frobenius algebras. In this work we develop a DPO rewriting formalism which is able to absorb multiple Frobenius structures, thus sensibly simplifying diagrammatic reasoning in the aforementioned applications. As a proof of concept, we use our formalism to describe an algorithm which computes the reduced form of a diagram of the theory of interacting bialgebras using a simple rewrite strategy. date: 2018-07-12 date_type: published publisher: ACM official_url: http://doi.acm.org/10.1145/3209108 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1570782 doi: 10.1145/3209108.3209137 isbn_13: 978-1-4503-5583-4 lyricists_name: Zanasi, Fabio lyricists_id: FZANA74 actors_name: Zanasi, Fabio actors_id: FZANA74 actors_role: owner full_text_status: public series: https://doi.org/10.1145/3209108.3209137 publication: LICS place_of_pub: Oxford, United Kingdom pagerange: 165-174 event_title: LICS '18 book_title: Proceedings of the 33rd Annual ACM/IEEE Symposium on Logic in Computer Science editors_name: Dawar, A editors_name: Grädel, E citation: Bonchi, F; Gadducci, F; Kissinger, A; Sobocinski, P; Zanasi, F; (2018) Rewriting with Frobenius.
