Quasihomogeneity of curves and the jacobian endomorphism ring.
Résumé
We give a quasihomogeneity criterion for Gorenstein curves. For complete intersections, it is related to the fi rst step of Vasconcelos' normalization algorithm. In the process, we give a simpli ed proof of the Kunz-Ruppert criterion.
