We construct a concrete example of a 1-parameter family of smooth projective geometrically integral varieties over an open subscheme of ℙ ℚ 1 such that there is exactly one rational fiber with no rational points. This makes explicit a construction of Poonen.

On construit un exemple concret d’une famille à un paramètre de variétés lisses, projectives, et géométriquement intègres sur un sous-schéma ouvert de ℙ ℚ 1 , de sorte qu’il y ait précisément une fibre rationnelle sans point rationnel. Ceci rend explicite une construction de Poonen.
