Etude topologique des formes logarithmiques fermées. (Topological study of closed logarithmic forms) (Q1100776)

We give a description of the foliation defined on an analytic complex manifold by a logarithmic closed one-form, with poles along a normal crossing divisor. For this, a notion of ``Clemens structure'' adapted to this situation is introduced. With this construction, we prove a result of topological triviality for a family of such forms.
