Nous démontrons un résultat général de finitude pour le groupe abélien ordonné des fonctions tropicales sur un squelette dans l’analytifié de Berkovich d’une variété algébrique. Notre approche consiste à travailler dans le cadre des complétés stables de variétés algébriques, une version modèle théorique de l’analytification de Berkovich, pour lesquels nous démontrons un énoncé similaire dont notre résultat est une conséquence.
We prove a general finiteness statement for the ordered abelian group of tropical functions on skeleta in Berkovich analytifications of algebraic varieties. Our approach consists in working in the framework of stable completions of algebraic varieties, a model-theoretic version of Berkovich analytifications, for which we prove a similar result, of which the former one is a consequence.
