[Attracteurs de valeurs extrêmes pour les copules 2-unimodales]
Nous déterminons les attracteurs des valeurs maximales pour les copules 2-unimodales (par rapport à (a,b)). Si (a,b)≠(1,1) ces attracteurs forment une famille de copules à deux paramètres généralisant celle de Cuadras–Augé alors que si (a,b)=(1,1) elles couvrent toutes les copules de valeurs maximales. Nous examinons aussi la relation entre l'unimodalité et les copules Archimax.
We determine maximum attractors for copulas star (or 2-) unimodal (about a point ). If (a,b)≠(1,1) these attractors form a two-parameter family of copulas extending that of Cuadras–Augé, whereas if (a,b)=(1,1) they cover all maximum value copulas. We also examine the relationship between unimodality and Archimax copulas.
