On Fuzzy Negations and Laws of Contraposition. Lattice of Fuzzy Negations

open access: yesFormalized Mathematics, 2023
Summary This the next article in the series formalizing the book of Baczyński and Jayaram “Fuzzy Implications”. We define the laws of contraposition connected with various fuzzy negations, and in order to make the cluster registration mechanism fully working, we construct some more non-classical examples of fuzzy implications.

A Fuzzy Take on the Logical Issues of Statistical Hypothesis Testing

open access: yesPhilosophies, 2021
Statistical Hypothesis Testing (SHT) is a class of inference methods whereby one makes use of empirical data to test a hypothesis and often emit a judgment about whether to reject it or not. In this paper, we focus on the logical aspect of this strategy,

Revision of Pseudo-Ultrametric Spaces Based on m-Polar T-Equivalences and Its Application in Decision Making

open access: yesMathematics, 2021
In mathematics, distance and similarity are known as dual concepts. However, the concept of similarity is interpreted as fuzzy similarity or T-equivalence relation, where T is a triangular norm (t-norm in brief), when we discuss a fuzzy environment ...

Interval-valued contractive fuzzy negations [PDF]

open access: yesInternational Conference on Fuzzy Systems, 2010
In this work we consider the concept of contractive interval-valued fuzzy negation, as a negation such that it does not increase the length or amplitude of an interval. We relate this to the concept of Lipschitz function. In particular, we prove that the only strict (strong) contractive interval-valued fuzzy negation is the one generated from the ...

A Method of Generating Fuzzy Implications from n Increasing Functions and n + 1 Negations

open access: yesMathematics, 2020
In this paper, we introduce a new construction method of a fuzzy implication from n increasing functions g i : [ 0 , 1 ] → [ 0 , ∞ ) ,   ( g ( 0 ) = 0 ) ( i = 1 , 2 , … , n ,   n   ∈ ℕ ) and n + 1 fuzzy negations

S-Implications on Complete Lattices and the Interval Constructor

open access: yesTrends in Computational and Applied Mathematics, 2008
The aim of this work is to present an approach of interval fuzzy logic based on complete lattices. In particular, we study the extensions of the notions of t-conorms, fuzzy negations and S-implication, from the unit interval to arbitrary complete ...

New Transitivity of Atanassov’s Intuitionistic Fuzzy Sets in a Decision Making Model

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2021
Atanassov’s intuitionistic fuzzy sets and especially his intuitionistic fuzzy relations are tools that make it possible to model effectively imperfect information that we meet in many real-life situations.

On Fuzzy Negations Generated by Fuzzy Implications

open access: yesFormalized Mathematics, 2020
Summary We continue in the Mizar system [2] the formalization of fuzzy implications according to the book of Baczyński and Jayaram “Fuzzy Implications” [1]. In this article we define fuzzy negations and show their connections with previously defined fuzzy implications [4] and [5] and triangular norms and conorms [6].

Ordinal Sums of De Morgan Triples

open access: yesTrends in Computational and Applied Mathematics, 2018
In this paper we consider the ordinal sum of the summands (a_i, b_i, T_i) ((a_i, b_i, S_i)), where (T_i)_{i\in I}$ $((S_i)_{i\in I}) are a family of t-(co)norms and $(]a_i, b_i[)_{i\in I}$ a family of nonempty, pairwise disjoint open subintervals of [0,1]
