Minimal resolution and stable reduction of X 0 (N)
Annales de l'Institut Fourier, Volume 40 (1990) no. 1, pp. 31-67.

Let N1 be an integer. Let X 0 (N) be the modular curve over Z, as constructed by Katz and Mazur. The minimal resolution of X 0 (N) over Z[1/6] is computed. Let p5 be a prime, such that N=p 2 M, with M prime to p. Let n=(p 2 -1)/2. It is shown that X 0 (N) has stable reduction at p over Q[p n], and the fibre at p of the stable model is computed.

Soit N1 un nombre entier. Soit X 0 (N) la courbe modulaire sur Z, construite par Katz et Mazur. On calcule la résolution minimale de X 0 (N) sur Z[1/6]. Soit p5 un nombre premier, tel que N=p 2 M, avec M premier à p. Soit n=(p 2 -1)/2. On montre que X 0 (N) a réduction stable en p sur Q[p n], et on calcule la fibre au-dessus de p du modèle stable.
