We use the reverse algebraisation paradigm: CHL is presented as the assertional logic of a point regular variety (whose structure theory is examined in detail) that turns out to be term equivalent to the variety of Heyting algebras. We provide Hilbert-style and Gentzen-style proof systems for CHL; moreover, we suggest a possible computational interpretation of its connexive conditional, and we revisit Kapsner's idea of superconnexivity.", "revisions": [ { "version": "v1", "updated": "2022-08-31T09:22:18.000Z" } ], "analyses": { "keywords": [ "intuitionistic logic", "revisit kapsners idea", "gentzen-style proof systems", "reverse algebraisation paradigm", "point regular variety" ], "note": { "typesetting": "TeX", "pages": 36, "language": "en", "license": "arXiv", "status": "editable" } } }
