The Calculus of Names—The Legacy of Jan Łukasiewicz

open access: yesAxioms
With his research on Aristotle’s syllogistic, Jan Łukasiewicz initiates the branch of logic known as the calculus of names. This field deals with axiomatic systems that analyse various fragments of the logic of names, i.e., that branch of logic that ...

Comparing Circular Histograms by Using Modulo Similarity and Maximum Pair-Assignment Compatibility Measure

open access: yesInternational Journal of Computational Intelligence Systems, 2017
Histograms are an intuitively understandable tool for graphically presenting frequency data that is available for and useful in modern data-analysis, this also makes comparing histograms an interesting field of research.

Geometry of Robinson consistency in Łukasiewicz logic [PDF]

open access: yes, 2007
We establish the Robinson joint consistency theorem for the infinite-valued propositional logic of Łukasiewicz. As a corollary we easily obtain the amalgamation property for MV-algebras-the algebras of Łukasiewicz logic: all pre-existing proofs of this ...

Aristotle’s Syllogistic as a Deductive System

open access: yesAxioms, 2020
Aristotle’s syllogistic is the first ever deductive system. After centuries, Aristotle’s ideas are still interesting for logicians who develop Aristotle’s work and draw inspiration from his results and even more from his methods.

A Logic for Dually Hemimorphic Semi-Heyting Algebras and its Axiomatic Extensions

open access: yesBulletin of the Section of Logic, 2022
The variety \(\mathbb{DHMSH}\) of dually hemimorphic semi-Heyting algebras was introduced in 2011 by the second author as an expansion of semi-Heyting algebras by a dual hemimorphism.

Aristote et la « logique formelle moderne » : sur quelques paradoxes de l’interprétation de Łukasiewicz

open access: yesPhilosophia Scientiæ, 2011
Łukasiewicz’s Aristotle’s Syllogistic was written from the standpoint of modern formal log ic as a correction of the traditional interpretations of Aristotle’s syllogistic.

A Common External Framework for Kleene and McCarthy Algebras

open access: yesMathematical Logic Quarterly, Volume 72, Issue 4, November 2026.
ABSTRACT Algebras of disjoint alternatives (ADAs), introduced by Manes, are extensions of McCarthy algebras by a unary operator acting as an oracle for the halting problem, and provide a semantics for the equational theory of the if–then–else construct.

Model pluralism for logic

open access: yesNoûs, Volume 60, Issue 1, Page 136-160, March 2026.
Abstract It is well‐recognized in the sciences that a multitude of nonequivalent models are used by researchers to fulfill a range of goals, even for the same target system, a result known broadly as model pluralism. The possibility of the same form of pluralism occurring in logic, however, has not been adequately considered.
