Soit l’ensemble des puissances parfaites rationnelles, et soit un sous-ensemble fini de . Nous prouvons l’existence d’un polynôme tel que . Ceci généralise un théorème récent de Gajović qui a démontré un résultat similaire pour les sous-ensembles finis de puissances parfaites entières. Notre approche fait appel à la résolution de l’équation de Fermat généralisée de signature dans [2, 4, 7], ainsi qu’à la finitude des puissances parfaites dans les suites récurrentes binaires non dégénérées, prouvée par Pethő et par Shorey et Stewart.
Let be the set of rational perfect powers, and let be a finite subset of . We prove the existence of a polynomial such that . This generalizes a recent theorem of Gajović who proved a similar result for finite subsets of integer perfect powers. Our approach makes use of the resolution of the generalized Fermat equation of signature in [2, 4, 7], as well as the finiteness of perfect powers in non-degenerate binary recurrence sequences, proved by Pethő and by Shorey and Stewart.
