On construit des structures d'algèbres amassées généralisées compatibles avec le crochet de Poisson sur le double de Drinfeld du group GLn muni de sa structure de Poisson–Lie usuelle. On en déduit une structure d'algèbre amassée généralisée sur GLn compatible avec l'image directe du crochet de Poisson dual.

We construct a generalized cluster structure compatible with the Poisson bracket on the Drinfeld double of the standard Poisson–Lie group GLn and derive from it a generalized cluster structure in GLn compatible with the push-forward of the dual Poisson–Lie bracket.
