WebAn infinitary proof theory is developed for modal logics whose models are coalgebras of polynomial functors on the category of sets. The canonical model method from modal logic is adapted to construct a final coalgebra for any polynomial functor. The ... Web7 de jan. de 2024 · Extending and generalizing the approach of 2-sequents (Masini, 1992), we present sequent calculi for the classical modal logics in the K, D, T, S4 spectrum. The systems are presented in a uniform way-different logics are obtained by tuning a single parameter, namely a constraint on the applicability of a rule. Cut-elimination is proved …

WebSome of the major areas of proof theory include structural proof theory, ordinal analysis, provability logic, reverse mathematics, proof mining, automated theorem proving, and … WebRelated work on modal proof theory. The history of modal proof theory and construc-tive modal logics is long and tumultuous, so we shall try to avoid the subject as much as possible. A more thorough discussion of modal -calculi may be found in [Kav16]. For a broader survey of the proof theory of modal logic we recommend [Neg11]. binding of isaac green tear
