Atanassov’s Intuitionistic Contractive Fuzzy Negations
2010In this work we consider the concept of contractive Atanassov’s intuitionistic mapping. In particular, we show that with our definitions, the only strict (strong) contractive negation is the standard one.

Moore Continuous n-Dimensional Interval Fuzzy Negations
2018 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2018n-dimensional fuzzy sets are an generalizing some extensions of fuzzy sets, such as, interval-valued fuzzy sets, interval-valued Atanassov intuitionistic fuzzy sets and fuzzy mul-tisets, where the membership values are n-truples of real numbers in the unit interval [0, 1] ordered in increasing order, called n-dimensional intervals.

On the negation of bipolar fuzzy conditions
2011 Annual Meeting of the North American Fuzzy Information Processing Society, 2011This paper deals with the negation operator in the context of a bipolar fuzzy relational algebra which makes it possible to handle bipolar fuzzy queries (involving flexible constraints and wishes) and relations. Several possible definitions of the negation are studied and assessed with respect to some desirable properties.

On antonym and negate in fuzzy logic
International Journal of Intelligent Systems, 1999The paper analyses the antonyms in natural language and the possibility to model their meaning using fuzzy set theory. The presentation is extensional, when the meaning of words of natural language is modeled using fuzzy sets being functions on some universe. A specific case is supposed when the universe is formed by an interval of real numbers.

Short Note: Some Hints on Fuzzy Logic’s Negation Functions
New Mathematics and Natural Computation, 2019This paper deals with how non-strong linguistic negations can be represented in Fuzzy Logic by means of Negation Functions. Even if the problem is not closed, the impossibility of representing by exhaustive Negation Functions those that are either weak, or intuitionistic, is proved. A hint on how to continue the study is presented.

General Negations for Residuated Fuzzy Logics
2014Involutive residuated negations are usually considered in residuated fuzzy logics and they are also based on continuous triangular norms. This paper introduces a generalization of these negations using flexible conjunctors, several properties of them and the corresponding disjunctive dual operators associated with the conjunctor.

Fuzzy Negation and Other Weak Fuzzy Connectives
2012This paper deals with some dependencies between fuzzy negations and other fuzzy connectives. The generalized laws of contradiction and excluded middle are considered. Methods for generating fuzzy negation from fuzzy conjunction, disjunction or fuzzy implication together with another fuzzy negation are also presented.

Interval Valued Versions of T-Conorms, Fuzzy Negations and Fuzzy Implications
2006 IEEE International Conference on Fuzzy Systems, 2006There exists infinitely many way to extend the classical prepositional connectives to the set [0,1] such that the behavior in their extremes are as in the classical logic. Still, is a consensus that it is not sufficient, demanding that these extensions also preserves some logical properties of the classical connectives.
