Jet schemes of complex plane branches and equisingularity
[Espaces des jets des branches planes complexes et équisingularité]
Annales de l'Institut Fourier, Tome 61 (2011) no. 6, pp. 2313-2336.

Pour m, nous déterminons les composantes irréductibles des m-èmes espaces des jets d’une branche plane complexe C et nous donnons des formules pour leur nombre N(m) et leurs codimensions, en fonction de m et des générateurs du semigroupe de C. Cette structure des espaces des jets détermine et elle est déterminée par le type topologique de C.

For m, we determine the irreducible components of the m-th Jet Scheme of a complex branch C and we give formulas for their number N(m) and for their codimensions, in terms of m and the generators of the semigroup of C. This structure of the Jet Schemes determines and is determined by the topological type of C.
