Opérateurs de Hecke pour \(\Gamma_ 0(N)\) et fractions continues. (Hecke operators for \(\Gamma_ 0(N)\) and continued fractions). (French) Zbl 0727.11020

Nous rappelons que Manin décrit l’homologie singulière relative aux pointes de la courbe modulaire \(X_ 0(N)\) comme un quotient du groupe \({\mathbb{Z}}^{({\mathbb{P}}^ 1({\mathbb{Z}}/N{\mathbb{Z}}))}\). En s’appuyant sur des techniques de fractions continues, nous donnons une expression indépendante de N d’un relèvement de l’action des opérateurs de Hecke de \(H_ 1(X_ 0(N),...,{\mathbb{Z}})\) sur \({\mathbb{Z}}^{({\mathbb{P}}^ 1({\mathbb{Z}}/N{\mathbb{Z}}))}\).
