Les concepts de « semi-anneau » et d’« hypersurface tropicale » sont étendus au cas des groupes ordonnés quelconques. Ensuite, nous definissons la « tropicalisation » d’un polynôme à coefficients dans un corps valué. Après une étude détaillée de l’opérateur de tropicalisation, nous donnons une généralisation du théorème de Kapranov aux corps algébriquement clos munis d’une valuation à valeurs dans un groupe ordonné.
The concepts of tropical semiring and tropical hypersurface, are extended to the case of an arbitrary ordered group. Then, we define the tropicalization of a polynomial with coefficients in a Krull-valued field. After a close study of the properties of the operator “tropicalization" we conclude with an extension of Kapranov’s theorem to algebraically closed fields together with a valuation over an ordered group.
