Abstract
We establish weak factorizations for a weighted Bergman space \(A^p_{\alpha }\), with \(1<p<\infty \), into two weighted Bergman spaces on the unit ball of \(\mathbb {C}^n\). To obtain this result, we characterize bounded Hankel forms on weighted Bergman spaces on the unit ball of \(\mathbb {C}^n\).
