Generic Modal Cut Elimination Applied to Conditional Logics [PDF]
Logical Methods in Computer Science, 2011 We develop a general criterion for cut elimination in sequent calculi for propositional modal logics, which rests on absorption of cut, contraction, weakening and inversion by the purely modal part of the rule system. Our criterion applies also to a wide

Cut-elimination for the mu-calculus with one variable [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 We establish syntactic cut-elimination for the one-variable fragment of the modal mu-calculus. Our method is based on a recent cut-elimination technique by Mints that makes use of Buchholz' Omega-rule.

Inducing syntactic cut-elimination for indexed nested sequents [PDF]
Logical Methods in Computer Science, 2018 The key to the proof-theoretic study of a logic is a proof calculus with a subformula property. Many different proof formalisms have been introduced (e.g. sequent, nested sequent, labelled sequent formalisms) in order to provide such calculi for the many

Fast Cut-Elimination using Proof Terms: An Empirical Study [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 Urban and Bierman introduced a calculus of proof terms for the sequent calculus LK with a strongly normalizing reduction relation. We extend this calculus to simply-typed higher-order logic with inferences for induction and equality, albeit without ...

Cut Elimination for Extended Sequent Calculi
Bulletin of the Section of Logic, 2023 We present a syntactical cut-elimination proof for an extended sequent calculus covering the classical modal logics in the \(\mathsf{K}\), \(\mathsf{D}\), \(\mathsf{T}\), \(\mathsf{K4}\), \(\mathsf{D4}\) and \(\mathsf{S4}\) spectrum.

The Structure of Differential Invariants and Differential Cut Elimination [PDF]
Logical Methods in Computer Science, 2012 The biggest challenge in hybrid systems verification is the handling of differential equations. Because computable closed-form solutions only exist for very simple differential equations, proof certificates have been proposed for more scalable ...

Cut Elimination in Multifocused Linear Logic [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 We study cut elimination for a multifocused variant of full linear logic in the sequent calculus. The multifocused normal form of proofs yields problems that do not appear in a standard focused system, related to the constraints in grouping rule ...

Cut-Simulation and Impredicativity [PDF]
Logical Methods in Computer Science, 2009 We investigate cut-elimination and cut-simulation in impredicative (higher-order) logics. We illustrate that adding simple axioms such as Leibniz equations to a calculus for an impredicative logic -- in our case a sequent calculus for classical type ...

Exponentials as Substitutions and the Cost of Cut Elimination in Linear Logic [PDF]
Logical Methods in Computer Science, 2023 This paper introduces the exponential substitution calculus (ESC), a new presentation of cut elimination for IMELL, based on proof terms and building on the idea that exponentials can be seen as explicit substitutions.

Cut elimination for knowledge logic with interaction
Lietuvos Matematikos Rinkinys, 2021 In the article the multimodal logic Tn with central agent interaction axiom is analysed. The Hilbert type calculi is presented, then Gentzen type calculi with cut is derived and the proof of cutelimination theorem is outlined.
