Champs aléatoires intermittents. Partie I : champs à accroissements symétriques

The purpose of this Note is to construct a natural family of random processes and fields having a multifractal character. Such objects play a crucial rôle in modelling turbulence and financial markets. In the present first part we present a model of a field with symmetric increments. To cite this article: J. Duchon, R.
