Abstract:

Dans cette note, on montre que les courbes, lisses connexes, de degré $d$ et genre $g$, tracées sur une surface quartique normale variable de $\mathbb {P}_3$, et n’y étant pas intersection complète, forment des familles de dimensions $\leq g+33$. Cette majoration est la meilleure possible. Comme application on prouve que le schéma de Hilbert des courbes lisses connexes de $\mathbb {P}_3$ de degré $12$ et genre $13$ est irréductible.
