WebAbstract. We introduce a \qualitative property" for Bott-Chern cohomology of complex non-K ahler manifolds, which is motivated in view of the study of the algebraic structure of Bott-Chern cohomology. We prove that such a property characterizes the validity of the @@-Lemma. This follows from a quantitative study of Bott-Chern cohomology.
