Weak factorization and Hankel forms for weighted Bergman spaces on the unit ball

We establish weak factorizations for a weighted Bergman space $A_{\text{a}}^p$, with $1<p<\mathrm{\infty }$, into two weighted Bergman spaces on the unit ball of ${\text{C}}^n$. To obtain this result, we characterize bounded Hankel forms on weighted Bergman spaces on the unit ball of ${\text{C}}^n$.
