LP, K3, and FDE as Substructural Logics [PDF]

open access: yes, 2017
Building on recent work, I present sequent systems for the non-classical logics LP, K3, and FDE with two main virtues. First, derivations closely resemble those in standard Gentzen-style systems.

Modular Labelled Sequent Calculi for Abstract Separation Logics

open access: yes, 2017
separation logics are a family of extensions of Hoare logic for reasoning about programs that manipulate resources such as memory locations. These logics are "abstract" because they are independent of any particular concrete resource model.

A simple sequent calculus for nominal logic [PDF]

open access: yes, 2013
Nominal logic is a variant of first-order logic that provides support for reasoning about bound names in abstract syntax. A key feature of nominal logic is the new-quantifier, which quantifies over fresh names (names not appearing in any values ...

A Measure of Inference in Classical and Intuitionistic Logics [PDF]

open access: yes, 2011
This paper presents a measure of inference in classical and intuitionistic logics inthe Gentzen-style sequent calculi. The measure for a proof of a sequent is the widthof the proof tree, that is, the number of leaves of the proof tree.

Experimental Study of Effect of Rough Bed on Sequent Depth Ratio of Hydraulic Jump on Adverse Slope [PDF]

open access: yesعلوم و مهندسی آبیاری, 2012
Hydraulic jump is one of the important phenomena in rapidly varied flow. Due to this phenomenon the energy loss, the upstream flow velocity significantly decreases.

Sequent and Hypersequent Calculi for Abelian and Lukasiewicz Logics [PDF]

open access: yes, 2002
We present two embeddings of infinite-valued Lukasiewicz logic L into Meyer and Slaney's abelian logic A, the logic of lattice-ordered abelian groups. We give new analytic proof systems for A and use the embeddings to derive corresponding systems for L ...

Gentzen and Temporal Sequents

open access: yesStudies in Logic, Grammar and Rhetoric
The paper presents a comparison of two generalised sequent calculi for temporal logics. In both cases the main technical solution is the multiplication of the sorts of sequents and, additionally, the application of some kind of labelling to formulae. The
