Gauduchon's form and compactness of the space of divisors
Résumé
We show that in a holomorphic family of compact complex connected manifolds parametrized by an irreducible complex space S, assuming that on a dense Zariski open set S * in S the fibres satisfy the ∂ ¯ ∂−lemma, then the algbraic dimension of each fibre in this family is at least equal to the minimal algebraic dimension of the fibres in S *. For instance, if each fibre in S * are Moishezon, then all fibres are Moishezon.
