Following the study of the arc structure of singularities, initiated b
y J. Nash, we give criteria for the existence of smooth curves on a su
rface singularity (S, O) and of smooth branches of its generic hyperpl
ane section. A natural partition of the set of smooth curves on (S, O)
into families as well as a description of each one of them by means o
f chains of infinitely near points and their associated maximal cycle
follow from these criteria.
