Generalization of Kalmar’s Proof of Deducibility in Two Valued Propositional Logic into Many Valued Logic

open access: yes, 2017
This paper focuses on the problem of constructing of some standard Hilbert style proof systems for any version of many valued propositional logic.

The Logic of Self-Organized Criticality

open access: yesStudia Humana, 2015
A consideration of non-classical logic in terms of classical one allows us to show a role of designated truth values. In this way we show that our version of non-classical many-valued logic can be based on the structure of genetic code.

Logical Determinacy versus Logical Contingency. The Case of Łukasiewicz’s Three-valued Logic

open access: yesStudia Humana, 2019
In constructing the three-valued logic, Jan Łukasiewicz was highly inspirited by the Aristotelian idea of logical contingency. Nevertheless, we can construct a four-valued logic for explicating the Stoic idea of logical determinacy.

On Jan Łukasiewicz’s many-valued logic and his criticism of determinism

open access: yesPhilosophia Scientiæ, 2011
The article deals with Jan Łukasiewicz’s thesis that the truth or falsity of some propositions about the future—future contingents—entails determinism.

From Boolean Valued Analysis to Quantum Set Theory: Mathematical Worldview of Gaisi Takeuti

open access: yesMathematics, 2021
Gaisi Takeuti introduced Boolean valued analysis around 1974 to provide systematic applications of the Boolean valued models of set theory to analysis. Later, his methods were further developed by his followers, leading to solving several open problems ...

A temporal semantics for Nilpotent Minimum logic

open access: yes, 2013
In [Ban97] a connection among rough sets (in particular, pre-rough algebras) and three-valued {\L}ukasiewicz logic {\L}3 is pointed out. In this paper we present a temporal like semantics for Nilpotent Minimum logic NM ([Fod95, EG01]), in which the logic

The Everett-Wheeler interpretation and the open future [PDF]

open access: yes, 2010
I discuss the meaning of probability in the Everett-Wheeler interpretation of quantum mechanics, together with the problem of defining histories. To resolve these, I propose an understanding of probability arising from a form of temporal logic: the ...

THE CLASS OF PERFECT TERNARY ARRAYS

open access: yesСистемный анализ и прикладная информатика, 2018
In recent decades, perfect algebraic constructions are successfully being use to signal systems synthesis, to construct block and stream cryptographic algorithms, to create pseudo-random sequence generators as well as in many other fields of science and ...

Eigenlogic: a Quantum View for Multiple-Valued and Fuzzy Systems

open access: yes, 2016
We propose a matrix model for two- and many-valued logic using families of observables in Hilbert space, the eigenvalues give the truth values of logical propositions where the atomic input proposition cases are represented by the respective eigenvectors.

Propositional Logics Complexity and the Sub-Formula Property [PDF]

open access: yes, 2015
In 1979 Richard Statman proved, using proof-theory, that the purely implicational fragment of Intuitionistic Logic (M-imply) is PSPACE-complete.
