A nominal rewriting system (Fernández et al., 2004) is a model of computation based on the nominal-set approach with a high expressive powerーit is capable of representing predicate logic, λ-calculus and so onーwhile retaining decidability of nominal unification, which is contrast to other formalizms in which higher-order unification is undecidable. Recently, an axiomatization of the α-equivalence relation using permutation fixed point constraints in stead of freshness constraints has been proposed by Ayala-Rincón et al. (2020). While the axiomatization is known to be useful for C-unification of nominal terms, its usability and effectiveness in nominal rewriting have not been well studied. In this presentation, we report on fundamental properties of fixed point constraints and propose a framework of nominal rewriting based on fixed point constraints. We moreover clarify basic properties of the proposed framework of nominal rewriting; in particular, we show that our framework generalizes the traditional framework of nominal rewriting based on freshness constraints.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"2","bibliographicIssueDates":{"bibliographicIssueDate":"2022-05-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"15"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
