One-Sided Sequent Systems for Nonassociative Bilinear Logic: Cut Elimination and Complexity
Bulletin of the Section of Logic, 2021 Bilinear Logic of Lambek amounts to Noncommutative MALL of Abrusci. Lambek proves the cut–elimination theorem for a one-sided (in fact, left-sided) sequent system for this logic.

Schema Complexity in Propositional-Based Logics
Mathematics, 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]
Logical 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-elimination for knowledge logics with interaction
Lietuvos 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 free sequent calculus for logic S5n(ED)
Lietuvos Matematikos Rinkinys, 2010 Hilbert style, Gentzen style sequent and Kanger style sequent calculi for logic S5n(ED) are considered in this paper. Gentzen style sequent calculus is constructed and its equivalence with Hilbert style system is proved, getting soundness and ...

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 ...

Cut-elimination and Redundancy-elimination by Resolution
Journal of Symbolic Computation, 2000 The authors propose a new cut-elimination procedure for classical predicate calculus LK. The basic formulation treats a particular case: \[ \text{if }A,\Gamma\vdash\Delta\text{ is derivable and }A\text{ is valid, then }\Gamma\vdash\Delta\text{ is derivable}.\tag{\(*\)} \] In general a cut like \(\Gamma\vdash B\); \(B,\Gamma\vdash\Delta/\Gamma \vdash ...

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

Logical Methods in Computer Science, 2013 We consider cut-elimination in the sequent calculus for classical first-order logic. It is well known that this system, in its most general form, is neither confluent nor strongly normalizing.
