Abstract: Let $ {A^{p,\alpha }}(B),{A^{q,\alpha }}(B)$ and $ {A^{l,\alpha }}(B)$ be weighted Bergman spaces on the unit ball of $ {{\text{C}}^{n}}\,(n > 1)$. We prove:

Theorem 1. If $ 1/l = 1/p + 1/q$ then $ {A^{p,\alpha }}(B) \cdot {A^{q,\alpha }}(B)$ is of first category in $ {A^{l,\alpha }}(B)$.

Theorem 2. Theorem 1 holds for Hardy spaces in place of weighted Bergman spaces. We also show that Theorems 1 and 2 hold for the polydisc $ {U^n}$ in place of $ B$.
