Abstract
Let k an algebraically closed field, char k = 0. Let C be an irreducible nonsingular curve such that rC = S ∩ F, \(r\in \mathbb {N}\), where S and F are two surfaces in \(\mathbb {P}^3\) and all the singularities of F are of the form z p = x ps − y ps, p prime, \(s\in \mathbb {N} \). We prove that C can never pass through such kind of singularities of a surface, unless r = pa, \(a\in \mathbb {N}\). These singularities are Kodaira singularities.
