This work studies the aggregation operators on the set of all possible membership degrees of typical hesitant fuzzy sets, which we refer to as H, as well as the action of H-automorphisms and analyzing the H-conjugate functions over such operators.Expand

This paper relates an interval generalization for t-norms given by the authors to the interval generalizations of automorphism given by M. Gehrke et al.Expand

In this paper, we review the definition and basic properties of the different types of fuzzy sets that have appeared up to now in the literature.Expand

We work with fuzzy Turing machines (FTMs) and we study the relationship between this computational model and classical recursion concepts such as computable functions, recursively enumerable (r.e.) sets and universality.Expand

This paper presents an analysis of interval-valued S-implications and interval- valued automorphisms, showing a way to obtain an interval-Validated S-Implication from two S- Implications, such that the resulting interval-value is said to be obtainable.Expand

This paper considers the existent results on residual implication induced by fuzzy conjunctions to introduce the concept of residual implication derived from overlap functions, denoted by R O -implication, preserving the residuation property.Expand
