Comportement extrémal des copules diagonales et de Bertino

open access: yesComptes Rendus. Mathématique, 2021
The maximal attractors of bivariate diagonal and Bertino copulas are determined under suitable regularity conditions. Some consequences of these facts are drawn, namely bounds on the maximal attractor of a symmetric copula with a given diagonal section ...
