In addition, we study aggregation operators that preserve various classes of generalized convexity on fuzzy sets. We focus our study on fuzzy subsets of the real line, so that given a mapping F : [0, 1] × [0,1] → [0,1], a fuzzy subset, say X, of the real line is said to be F-convex if for any x,y,z ∈ R such that x ≤ y ≤ z, it holds that μX(y) ≥ F(μX(x),μX(z)), where μX : R → [0,1] stands here for the membership function that defines the fuzzy set X. We study the existence of such sets paying attention to different classes of aggregation operators (that is, the corresponding functions F , as above), and preserving F -convexity under aggregation of fuzzy sets. Among those typical classes, triangular norms T will be analyzed, giving rise to the concept of norm convexity or T-convexity, as a particular case of F-convexity. Other different kinds of generalized convexities will also be discussed as a by-product Kategória publikačnej činnosti ADC Číslo archívnej kópie 40454 Katal.org.

Characteri- zation of pairs M,N for the family of MN-convex (MN-concave) functions consisting of all functions and partial characterization of pairs M,N for the family of MN-convex functions consisting of all constant functions will be presented. The condition of MN-convexity was proposed by Aumann in 1933. It was convexity with respect to arbitrary binary means M and N (abbreviated to MN-convexity). Recently many authors have considered this notion with suitable pairs of means. Here aggregation functions M,N will be used for this type of convexity and concavity Kategória publikačnej činnosti ADC Číslo archívnej kópie 40468 Katal.org.

Based on such set of evaluation we construct a fuzzy quantity on X2 describing the result of this evaluation. We show that assuming any triangular norm bounded from above by the Lukasiewicz triangular norm we obtain a fuzzy metric space. We show that for the minimum t-norm the resulting structure need not be a fuzzy metric space Kategória publikačnej činnosti AFC Číslo archívnej kópie 31877 Katal.org.
