The Basics of Display Calculi [PDF]

open access: yes, 2017
The aim of this paper is to introduce and explain display calculi for a variety of logics. We provide a survey of key results concerning such calculi, though we focus mainly on the global cut elimination theorem.

Semantic A-translation and Super-consistency entail Classical Cut Elimination [PDF]

open access: yes, 2013
We show that if a theory R defined by a rewrite system is super-consistent, the classical sequent calculus modulo R enjoys the cut elimination property, which was an open question.

A Cut-Free Sequential System for the Propositional Modal Logic of Finite Chains [PDF]

open access: yes, 1983
The main purpose of this paper is to give a cut-free Gentzen-type sequential system for K4.3G of finite chains.

Cut-elimination and a permutation-free sequent calculus for intuitionistic logic [PDF]

open access: yes, 1998
We describe a sequent calculus, based on work of Herbelin's, of which the cut-free derivations are in 1-1 correspondence with normal natural deduction proofs of intuitionistic logic.

Reverse mathematics and well-ordering principles [PDF]

open access: yes, 2011
The paper is concerned with generally Pi^1_2 sentences of the form 'if X is well ordered then f(X) is well ordered', where f is a standard proof theoretic function from ordinals to ordinals.

Cut-elimination for the modal Grzegorczyk logic via non-well-founded proofs

open access: yes, 2017
We present a sequent calculus for the modal Grzegorczyk logic Grz allowing non-well-founded proofs and obtain the cut-elimination theorem for it by constructing a continuous cut-elimination mapping acting on these proofs.Comment: WOLLIC'17, 12 pages, 1 ...

A Cut-Free Sequent Calculus for Defeasible Erotetic Inferences [PDF]

open access: yes, 2018
In recent years, the effort to formalize erotetic inferences (i.e., inferences to and from questions) has become a central concern for those working in erotetic logic. However, few have sought to formulate a proof theory for

Dual-Context Calculi for Modal Logic [PDF]

open access: yes, 2020
We present natural deduction systems and associated modal lambda calculi for the necessity fragments of the normal modal logics K, T, K4, GL and S4. These systems are in the dual-context style: they feature two distinct zones of assumptions, one of which

A New Linear Logic for Deadlock-Free Session-Typed Processes [PDF]

open access: yes, 2018
The π -calculus, viewed as a core concurrent programming language, has been used as the target of much research on type systems for concurrency. In this paper we propose a new type system for deadlock-free session-typed π -calculus processes, by ...

Algorithmic Introduction of Quantified Cuts

open access: yes, 2014
We describe a method for inverting Gentzen's cut-elimination in classical first-order logic. Our algorithm is based on first computign a compressed representation of the terms present in the cut-free proof and then cut-formulas that realize such a ...
