On the distributivity between t-norms and t-conorms

Fuzzy Sets and Systems, 2004
The paper deals with conditions and consequences of distributivity between t-norms and t-conorms defined on a general closed interval (rather than on \([0,1]\)). The research is motivated by the problems connected with the application of those concepts in fuzzy set theory (with the operations of intersection and union) and in the Forte-de Feriet ...

EXTREMAL k-LIPSCHITZ t-CONORMS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2006
Class of k-Lipschitz t-conorms is shown to have no strongest element for k > 1. Pointwise supremum of the class of k-Lipschitz t-conorms is introduced and the best approximation of this supremum by k-Lipschitz t-conorm is constructed.

Reducing t-norms and augmenting t-conorms

International Journal of General Systems, 2002
We study here the behavior of the t-norms at the point (1/2, 1/2). We indicate why this point can be considered as significant in the specification of t-norms. Then, we suggest that the image of this point can be used to classify the t-norms. We consider some usual examples. We also study the case of parameterized t-norms.

Nestings of T–Conorms

2009
This paper deals with a new method to construct a new t---conorm from two previous ones, by what we call a nesting procedure. After some general considerations about this method, we study those t---conorms obtained by nesting appropriate t---conorms in the basic maximum, drastic and Lukasiewicz t---conorms.

Some properties of t-conorm fuzzy additives

Proceedings Joint 9th IFSA World Congress and 20th NAFIPS International Conference (Cat. No. 01TH8569), 2002
In this paper, we introduce new concepts of S-fuzzy additive and S/sub w/-fuzzy additive measures and discuss some properties of S-possibility measures and their dual T-necessity measures.

Propositional Belief Merging with T-conorms

2017
We analyze in this paper the impact of introducing fuzzy T-conorm operators in the area of belief merging. There are mainly two subclasses of merging operators: the utilitarian and the egalitarian ones. We prove that a T-conorm merging operator can be included in the subtype of egalitarian operators.

On Migrative t-Conorms and Uninorms

2012
In this paper the notions of α-migrative t-conorms over a fixed t-conorm S 0, and α-migrative uninorms over another fixed uninorm U 0 with the same neutral element are introduced. All continuous t-conorms that are α-migrative over the maximum, the probabilistic sum and the Łukasiewicz t-conorm are characterized. Uninorms belonging to one of the classes

Multiplikation und t-Conorm-Integral

2002
Der Schwerpunkt dieser Arbeit liegt in der Untersuchung multiplikationsähnlicher Abbildungen. Diese sogenannten Pseudo-Multiplikationen werden axiomatisch charakterisiert und in Verbindung mit Pseudo-Additionen gebracht, für die stetige, aber nicht notwendigerweise archimedische t-Conormen gewählt werden.
