The minimal formal model of a curve singularity is zero-dimensional
Résumé
The minimal formal model of a curve singularity describes the non-trivial part of the
infinitesimal deformations of the Puiseux parametrizations of the singularity.
We show that it is of dimension zero, and effectively computable. We also show that it parameterizes
the deformations of the normalization morphism which leave the local ring of the singularity fixed.
