Inferences Between Buridan’s Modal Propositions

open access: yesProblemos, 2022
In recent years modal syllogistic provided by 14th century logician John Buridan has attracted increasing attention of historians of medieval logic. The widespread use of quantified modal logic with the apparatus of possible worlds semantics in current ...

First-order logic learning in artificial neural networks [PDF]

open access: yes, 2010
Artificial Neural Networks have previously been applied in neuro-symbolic learning to learn ground logic program rules. However, there are few results of learning relations using neuro-symbolic learning.

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.

Finite-Degree Predicates and Two-Variable First-Order Logic [PDF]

open access: yes, 2015
We consider two-variable first-order logic on finite words with a fixed number of quantifier alternations. We show that all languages with a neutral letter definable using the order and finite-degree predicates are also definable with the order predicate

Learning Concepts Definable in First-Order Logic with Counting [PDF]

open access: yesLogical Methods in Computer Science
We study Boolean classification problems over relational background structures in the logical framework introduced by Grohe and Turán (TOCS 2004). It is known (Grohe and Ritzert, LICS 2017) that classifiers definable in first-order logic over structures ...

A herbrandized functional interpretation of classical first-order logic [PDF]

open access: yes, 2017
We introduce a new typed combinatory calculus with a type constructor that, to each type σ, associates the star type σ^∗ of the nonempty finite subsets of elements of type σ.

A note on the expressive power of linear orders [PDF]

open access: yes, 2011
This article shows that there exist two particular linear orders such that first-order logic with these two linear orders has the same expressive power as first-order logic with the Bit-predicate FO(Bit). As a corollary we obtain that there also exists a

One Quantifier Alternation in First-Order Logic with Modular Predicates [PDF]

open access: yes, 2014
Adding modular predicates yields a generalization of first-order logic FO over words. The expressive power of FO[

Explaining the undecidability of first-order logic

open access: yesZagadnienia Filozoficzne w Nauce
Turing proved the unsolvability of the decision problem for first-order logic (Entscheidungsproblem) in his famous paper On Computable Numbers, with an Application to the Entscheidungsproblem.

First order logic to set requirements for secure code execution

open access: yesТруды Института системного программирования РАН, 2018
Currently the problem of information security during designing and exploiting the objects of critical information infrastructure is paid special attention to.
