Expanding the Realm of Systematic Proof Theory
Résumé
This paper is part of a general project of developing a sys- tematic and algebraic proof theory for nonclassical logics. Generaliz- ing our previous work on intuitionistic-substructural axioms and single- conclusion (hyper)sequent calculi, we define a hierarchy on Hilbert ax- ioms in the language of classical linear logic without exponentials. We then give a systematic procedure to transform axioms up to the level P3 of the hierarchy into inference rules in multiple-conclusion (hy- per)sequent calculi, which enjoy cut-elimination under a certain con- dition. This allows a systematic treatment of logics which could not be dealt with in the previous approach. Our method also works as a heuristic principle for finding appropriate rules for axioms located at levels higher than P3 . The case study of Abelian and Lukasiewicz logic is outlined.
