FLcom is a fuzzy propositional logic with contradictory negation, opposite negation and medium negation which corresponds to fuzzy set FScom. Based on theories of FLcom, this paper took a financial decision making for example, adopted Distance Ratio Function to give an evaluation to fuzzy propositional, gave a method to ascertain value of ( in the ...

Interval Negation in Fuzzy Logics
NAFIPS 2007 - 2007 Annual Meeting of the North American Fuzzy Information Processing Society, 2007This paper continues investigation of systems of fuzzy interval logics based on the Checklist Paradigm semantics of Bandler and Kohout. The paper looks at the alternative negations that may appear in the interval system rti\. In the previous papers dealing with checklist paradigm based interval systems the 2ary connectives were the interval connectives

Fuzzy Implications Generating from Fuzzy Negations
2018A basic building block in the foundation of fuzzy neural networks is the theory of fuzzy implications. Fuzzy implications play a crucial role in this topic. The aim of this paper is to find a new method of generating fuzzy implications. based on a given fuzzy negation.

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.

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.

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.

On Fuzzy Propositional Logic with Different Negations
2013Pan pointed out that there are three kinds of different negations: contradictory negation, opposite negation and medium negation. He also proposed the novel fuzzy set FScom with the above three kinds of negations, followed by one improved fuzzy set IFScom that is established based on FScom.
