Abstract
Let be a positive -closed current of bidimension on a projective manifold of dimension We show that for every the set of points of where the Lelong number of is larger or equal to is an analytic subset of dimension at most of Moreover, the following Siu decomposition holds where is a (possibly empty) finite or countable family of compact analytic curves in and is a positive -closed current of bidimension on whose Lelong number vanishes outside a finite or countable set. As a consequence, the cohomology class of every positive -closed current of bidimension on which does not give mass to any proper analytic set, belongs to the Poincar\'e dual of the effective cone of
