Transformations of Copulas and Quasi-Copulas
2004Transformations 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 ...

This article is a survey of quasi–copulas. The genesis, the history and the properties of quasi–copulas are presented, with special emphasis on their characterisation and on recent results. The presentation will also highlight the key part played by Roger Nelsen in all stages of the development of the theory.

Abstract We review the notion of a quasi-copula and using quasi-copulas we induce in [0,1] some large families of metrics which show to have some interesting probabilistic interpretations.

Quasi-Copulas on Discrete Scales
2006In the paper the structure of quasi-copulas on discrete scales is studied. A special attention is given to the study of quasi-copulas with diagonal section. The cardinality of the set of quasi-copulas on L (n) determined univocally by the corresponding diagonal section is shown to be the Fibonacci number p n.

Compatibility of Three Bivariate Quasi-Copulas: Applications to Copulas
2004In this paper we discuss the existence of trivariate copulas or quasi-copulas with prescribed three bivariate margins The case of quasi-copulas is completely solved. With respect to copulas, we provide a partial response to an interesting question posed in [8]. Several examples illustrate our results.
