Transformations isotropes des germes de feuilletages holomorphes

Abstract

AbstractGiven Fω a germ of holomorphic singular foliation at the origin of Cn defined by an equation ω=0 (with ω∧dω=0), we are interested in describing the group of isotropic transformations of Fω, i.e., the group of those germs Φ of diffeomorphisms at the origin of Cn that satisfy Φ∗ω∧ω=0
