Abstract

Transformations of aggregation operators preserving the class of copulas and quasi-copulas, respectively, are shown to be concave automorphisms of the unit interval. Attractors of copulas are discussed, special attention being paid to power transformations and the relationship between the corresponding attractors and the so-called maximum attractor (quasi-)copulas. The class of quasi-copulas stable under power transformations is characterized, and it is conjectured that it coincides with the class of all maximum attractor quasi-copulas. Also, examples of copulas not belonging to the maximum domain of attraction of any copula are provided.
