The distributivity condition for uninorms and t-operators

M Mas, G Mayor, J Torrens - Fuzzy Sets and Systems, 2002 - Elsevier
In this work we study the functional equation given by the distributivity condition:[Formula:
see text] where the unknown functions F, G are uninorms and/or t-operators. We …

Nullnorms on bounded lattices

F Karacal, MA Ince, R Mesiar - Information Sciences, 2015 - Elsevier
Nullnorms are generalization of triangular norms and triangular conorms with a zero
element in the interior of the unit interval. In this paper, we generalize nullnorms to an …

A survey on the existing classes of uninorms

M Mas, S Massanet, D Ruiz-Aguilera… - Journal of Intelligent & …, 2015 - content.iospress.com
This paper wants to be a compilation of the different existing classes of uninorms. From their
introduction, uninorms have been extensively studied not only as aggregation operators but …

Distributivity between uninorms and nullnorms

J Drewniak, P Drygaś, E Rak - Fuzzy Sets and Systems, 2008 - Elsevier
Recently the distributivity equation was investigated in families of certain operations (eg
triangular norms, conorms, uninorms and nullnorms). Generally, the assumption of …

Structure of n-uninorms

P Akella - Fuzzy Sets and Systems, 2007 - Elsevier
In this paper we study binary operators on [0, 1] which are associative, monotone non-
decreasing in both variables and commutative (AMC) with neutral element. In this work, we …

Distributivity between semi-t-operators and semi-nullnorms

P Drygaś - Fuzzy Sets and Systems, 2015 - Elsevier
Recently the distributivity equation was discussed in families of certain operations (eg
triangular norms, conorms, uninorms and nullnorms). In this paper we describe the solutions …

Distributivity equation in the class of 2-uninorms

P Drygaś, E Rak - Fuzzy Sets and Systems, 2016 - Elsevier
This paper is mainly devoted to solving the functional equation of distributivity between
aggregation operators with 2-neutral element. Our investigations are motivated by the …

The modularity condition for overlap and grouping functions

YM Wang, HW Liu - Fuzzy Sets and Systems, 2019 - Elsevier
This paper is mainly devoted to investigating the modularity condition for overlap and
grouping functions, which may have neither neutral elements nor associativity. At present …

Some further results about uninorms on bounded lattices

B Zhao, T Wu - International Journal of Approximate Reasoning, 2021 - Elsevier
The main purpose of this paper is to solve the problem proposed by Çaylı about uninorms
on bounded lattices and build close relationships among uninorms constructed in this paper …
