The Role of Quantifier Alternations in Cut Elimination

open access: yesNotre Dame Journal of Formal Logic, 2003
Extending previous results from the author's master's thesis, subsequently published in the proceedings of CSL 2003, on the complexity of cut elimination for the sequent calculus LK, we discuss the role of quantifier alternations and develop a measure ...

Exponentials as Substitutions and the Cost of Cut Elimination in Linear Logic [PDF]

open access: yesLogical 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.

Analytic Non-Labelled Proof-Systems for Hybrid Logic: Overview and a couple of striking facts

open access: yesBulletin of the Section of Logic, 2022
This paper is about non-labelled proof-systems for hybrid logic, that is, proofsystems where arbitrary formulas can occur, not just satisfaction statements.

Cut elimination by unthreading

open access: yesArchive for Mathematical Logic, 2023
AbstractWe provide a non-Gentzen, though fully syntactical, cut-elimination algorithm for classical propositional logic. The designed procedure is implemented on $$\textsf{GS4}$$ GS 4 , the one-sided version of Kleene’s sequent system $$\textsf{G4}$$

Schema Complexity in Propositional-Based Logics

open access: yesMathematics, 2021
The essential structure of derivations is used as a tool for measuring the complexity of schema consequences in propositional-based logics. Our schema derivations allow the use of schema lemmas and this is reflected on the schema complexity.

Quasipolynomial Normalisation in Deep Inference via Atomic Flows and Threshold Formulae [PDF]

open access: yesLogical Methods in Computer Science, 2016
Je\v{r}\'abek showed that cuts in classical propositional logic proofs in deep inference can be eliminated in quasipolynomial time. The proof is indirect and it relies on a result of Atserias, Galesi and Pudl\'ak about monotone sequent calculus and a ...

Cut-Free Gentzen Sequent Calculi for Tense Logics

open access: yesAxioms, 2023
The cut-free single-succedent Gentzen sequent calculus GKt for the minimal tense logic Kt is introduced. This sequent calculus satisfies the displaying property.

Cut-elimination for knowledge logics with interaction

open access: yesLietuvos Matematikos Rinkinys, 2008
In the article, multimodal logics K4n and S4n with the central agent axiom are analysed. The Hilbert type calculi are presented, then the Gentzen type calculi with cut are derived, and the proofs of the cut-eliminationtheorems are outlined.

Cut-Simulation and Impredicativity [PDF]

open access: yesLogical 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 ...

Confluence for classical logic through the distinction between values and computations [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2014
We apply an idea originated in the theory of programming languages - monadic meta-language with a distinction between values and computations - in the design of a calculus of cut-elimination for classical logic.
