Fregean logics

open access: yes, 2004
According to Frege's principle the denotation of a sentence coincides with its truth-value. The principle is investigated within the context of abstract algebraic logic, and it is shown that taken together with the deduction theorem it characterizes ...

SEQUENTIAL CALCULI FOR MANY-VALUED LOGICS WITH EQUALITY DETERMINANT [PDF]

open access: yes, 2004
We propose a general method of constructing sequential calculi with cut elimination property for propositional finitely-valued logics with equality determinant.

Definitional equivalence and algebraizability of generalized logical systems

open access: yesAnnals of Pure and Applied Logic, 1999
The author introduces and studies a concept of algebraizable sequential logic, a generalized notion of a logical system that covers, on a uniform basis, sequential systems and the quasi-equational theories of quasivarieties in Mal'tsev's sense. The author defines a concept of equivalence between generalized logics so that a logic is considered to be ...

Glivenko theorems revisited [PDF]

open access: yes, 2009
Glivenko-type theorems for substructural logics (over FL) are comprehensively studied in the paper (GO06b). Arguments used there are fully algebraic, and based on the fact that all substructural logics are algebraizable (see (GO06a) and also (GJKO07) for

Logics of Formal Inconsistency Enriched with Replacement: An Algebraic and Modal Account

open access: yes, 2022
One of the most expected properties of a logical system is that it can be algebraizable, in the sense that an algebraic counterpart of the deductive machinery could be found.

Gaggles, Gentzen and Galois: A Proof Theory for Algebraizable Logics

open access: yes, 1995
We show how the Gaggle Theory of Dunn gives a Gentzen-style proof theory for many algebraizable logics via the Display Logic of Belnap. At the heart of both systems lie the algebraic notions of residuation, Galois connections, and their duals ...

Operators and strong versions of sentential logics in Abstract Algebraic Logic [PDF]

open access: yes, 2016
This dissertation presents the results of our research on some recent devel-opments in Abstract Algebraic Logic (AAL), namely on the Suszko operator, the Leibniz filters, and truth-equational logics. Part I builts and develops an abstract framework which

A categorial foundation for a representation theory of logics

open access: yes, 2016
Neste trabalho estabelecemos uma base teórica para a construção de uma teoria de rep- resentação de lógicas proposicionais. Iniciamos identificando uma relação precisa entre a categoria das lógicas (Blok-Pigozzi) algebrizáveis e a categoria de suas ...

ALGEBRAS AND MATRICES FOR ANNOTATED LOGICS ∗

open access: yes, 2008
We study the matrices, reduced matrices and algebras associated to the systems SALτ of structural annotated logics. In previous papers, these systems were proven algebraizable in the finitary case and the class of matrices analyzed here was proven to be ...
