The Modelwise Interpolation Property of Semantic Logics

open access: yesBulletin of the Section of Logic, 2023
In this paper we introduce the modelwise interpolation property of a logic that states that whenever \(\models\phi\to\psi\) holds for two formulas \(\phi\) and \(\psi\), then for every model \(\mathfrak{M}\) there is an interpolant formula \(\chi ...

Intuitionistic quantum logic of an n-level system [PDF]

open access: yes, 2009
A decade ago, Isham and Butterfield proposed a topos theoretic approach to quantum mechanics, which meanwhile has been extended by Doering and Isham so as to provide a new mathematical foundation for all of physics.

Algebraic theories for contextual pre-nets

open access: yes, 2003
The algebraic models of computation for contextual nets that have been proposed in the literature either rely on a non-free monoid of objects, or introduce too many fictitious behaviors that must be somewhat filtered out.

Conversion between Logic and Algebraic Expressions of Boolean Control Networks

open access: yesApplied Sciences, 2020
The conversion between logic and algebraic expressions of Boolean control networks plays a worthy role in the analysis and design of digital circuits. In this paper, for a single Boolean function, a direct conversion between the minterm canonical form ...

A Logic for Algebraic Effects [PDF]

open access: yes2008 23rd Annual IEEE Symposium on Logic in Computer Science, 2008
We present a logic for algebraic effects, based on the algebraic representation of computational effects by operations and equations. We begin with the a-calculus, a minimal calculus which separates values, effects, and computations and thereby canonises the order of evaluation.

Relational and Allegorical Semantics for Constraint Logic Programming [PDF]

open access: yes, 2012
El cálculo de relaciones binarias fue creado por De Morgan en 1860 para ser posteriormente desarrollado en gran medida por Peirce y Schröder. Tarski, Givant, Freyd y Scedrov demostraron que las álgebras relacionales son capaces de formalizar la lógica de

Regular Cost Functions, Part I: Logic and Algebra over Words [PDF]

open access: yesLogical Methods in Computer Science, 2013
The theory of regular cost functions is a quantitative extension to the classical notion of regularity. A cost function associates to each input a non-negative integer value (or infinity), as opposed to languages which only associate to each input the ...

Features and Fluents for Logic Programming: Non-simulative Algebraic Semantics [PDF]

open access: yes, 2013
A Non-simulative Algebraic Semantics is defined and its range of applicability is proven to be the K-RACi class of the Features and Fluents framework.

Intuitionistic Layered Graph Logic: Semantics and Proof Theory [PDF]

open access: yesLogical Methods in Computer Science, 2018
Models of complex systems are widely used in the physical and social sciences, and the concept of layering, typically building upon graph-theoretic structure, is a common feature.
