Remarks on Seshadri constants of vector bundles
Annales de l'Institut Fourier, Tome 50 (2000) no. 3, pp. 767-780.

Nous donnons une borne inférieure pour les constantes de Seshadri des fibrés vectoriels amples dépendant uniquement des propriétés numériques des classes de Chern et d’une condition de “stabilité”

We give a lower bound for the Seshadri constants of ample vector bundles which depends only on the numerical properties of the Chern classes and on a “stability” condition.
