On the system CL12 of computability logic [PDF]

open access: yesLogical Methods in Computer Science, 2015
Computability logic (see http://www.csc.villanova.edu/~japaridz/CL/) is a long-term project for redeveloping logic on the basis of a constructive game semantics, with games seen as abstract models of interactive computational problems.

A refinement of the Craig-Lyndon Interpolation Theorem for classical first-order logic (with identity) [PDF]

open access: yes, 2017
We refine the interpolation property of classical first-order logic (without identity and without functionsymbols), showing that if G & , & D and G $ D then there is an interpolant c, constructed using onlynon-logical vocabulary common to both ...

Typed realizability for first-order classical analysis [PDF]

open access: yesLogical Methods in Computer Science, 2015
We describe a realizability framework for classical first-order logic in which realizers live in (a model of) typed {\lambda}{\mu}-calculus.

The validity degree vectors of formulae in two-valued predicate logic [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2015
By means of infinite product of uniformly distributed probability spaces of cardinal , the concept of -validity degrees and validity degree vectors of formulae in two-valued predicate logic are introduced. It is proved that the validity degree vectors of

Intuitionistic completeness for first order classical logic [PDF]

open access: yesJournal of Symbolic Logic, 1999
AbstractIn the past sixty years or so, a real forest of intuitionistic models for classical theories has grown. In this paper we will compare intuitionistic models of first order classical theories according to relevant issues, like completeness (w.r.t.

Game Semantics in Teaching of Classical First Order Predicate Logic to Stu- dents of Computer Science

open access: yesMATEC Web of Conferences, 2018
Game-theoretical interpretation of logical semantics has been first suggested in 1950s. Although it is well know among professionals, it is often excluded from introductory courses in logic.

Independence and games

open access: yesPhilosophia Scientiæ, 2005
Hintikka and Sandu have developed IF logic as a genuine alternative to classical first-order logic : liberalizing dependence schemas between quantifiers, IF would carry out all the ideas already underlying classical logic.

Admissibility, compatibility, and deducibility in first-order sequent logics [PDF]

open access: yesComputer Science Journal of Moldova, 2015
The paper is about the notions of admissibility and compatibility and their significance for deducibility in different sequent logics including first-order classical and intuitionistic ones both without and with equality and, possibly, with modal rules.

THE LOGICAL SYSTEM OF FREGE'S GRUNDGESTZE: A RATIONAL RECONSTRUCTION

open access: yesManuscrito, 2015
This paper aims at clarifying the nature of Frege's system of logic, as presented in the first volume of the Grundgesetze . We undertake a rational reconstruction of this system, by distinguishing its propositional and predicate fragments. This allows us
