FEUILLETAGES ET ACTIONS DE GROUPES SUR LES ESPACES PROJECTIFS

摘要

A lioloniorphie folia-tion F on a. compact complex manifold hi is said t(i ho an L-foliation if there exists an action of a complex Lie group (V such that the generic loaf of .F coincides with the gc'norio orbit of G. We study L-foliations ol codiinonsion one. in particular in projective space, in the spirit of classical invariant theory, but lion1 the invariants are sometimes transcendental ones. Wo give a list of example's and general properties. Some classification results are obtained in low dimensions.
