NONLINEAR NYBERG CONSTRUCTION TRANSFORMS OVER ISOMORPHIC REPRESENTATIONS OF FIELDS GALOIS

open access: yesСистемный анализ и прикладная информатика, 2017
Further development of cryptographic algorithms based on the principles of many-valued logic requires more accurate research of non-binary cryptographic primitives – S-boxes.

Equality Logic

open access: yesBulletin of the Section of Logic, 2020
In this paper, we introduce and study a corresponding logic to equality-algebras and obtain some basic properties of this logic. We prove the soundness and completeness of this logic based on equality-algebras and local deduction theorem.

Many-Valued Logic, Partiality, and Abstraction in Formal Specification Languages [PDF]

open access: yes, 2005
The purpose of this article is to clarify the role that many-valued logic can or should play in formal specification of software systems for modeling partiality. We analyse a representative set of specification languages.

Matrix- based logic for avoiding paradoxes and its paraconsistent alternative

open access: yesManuscrito, 2011
The present article shows that there are consistent and decidable many- valued systems of propositional logic which satisfy two or all the three criteria for non- trivial inconsistent theories by da Costa (1974).

On Scott’s semantics for many-valued logic [PDF]

open access: yes, 2020
The semantics in ordered abelian groups Scott proposed for Łukasiewicz’s many-valued logic fails to be sound for one direction of one of the rules Scott gave for implication.

Partial-valued logic [PDF]

open access: yes, 1980
PART I (Partial-valued Languages): In Chapter I we consider modes of sentence composition and ask what 'truth-functionality' is functionality in two values, when there is also a third classification for meaningful sentences, An answer to this question ...

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 ...

On neutrosophic uninorms [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
Uninorm generalizes the notion of t-norm and t-conorm in fuzzy logic theory. They are three increasing, commutative and associate operators having one neutral element. However, such specific value identifies the kind of operator it is; t-norms have the 1

Shadowing in Many-Valued Nested Structures [PDF]

open access: yes, 2020
Belief shadowing is a relatively recent approach to belief change. In essence, shadowing depends on accepting beliefs of others at the expense of dismissing, perhaps temporarily, some of the own ones.

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.
