Pour m∈ℕ, 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∈ℕ, 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.
