OPPOSITE DIAGONAL SECTIONS OF QUASI-COPULAS AND COPULAS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2009
In this paper, we study opposite diagonal sections of quasi-copulas and copulas. The best-possible upper bound for the set of copulas with a given opposite diagonal section being known, we focus on the best-possible lower bound, which in general is a quasi-copula. Moreover, it exhibits an interesting type of bivariate symmetry called opposite symmetry.

On copulas that generalize semilinear copulas

Kybernetika, 2012
Summary: We study a wide class of copulas which generalizes well-known families of copulas, such as the semilinear copulas. We also study corresponding results for the case of quasi-copulas.

Transformations of Copulas and Quasi-Copulas

2004
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 ...
