Abstract

In this paper we study some functionals operating on the set of the n-copulas defined on [0,1]n. Conditions under which such functionals are well defined are determined and some counterexamples are described. The study of the fixed points (n-copulas) for these functionals is also considered, and, finally, some open problems are presented.
