| Given $n\geq1$ and $r\in[0,\,1),$ we consider the set $\mathcal{R}_{n,\, r}$ of rational functions having at most $n$ poles all outside of $\frac{1}{r}\mathbb{D},$ were $\mathbb{D}$ is the unit disc of the complex plane. We give an asymptotically sharp Bernstein-type inequality for functions in $\mathcal{R}_{n,\, r}\:$ (as n tends to infinity and r tends to 1-) in weighted Bergman spaces with ''polynomially'' decreasing weights. We also prove that this result can not be extended to weighted Bergman spaces with ''super-polynomially'' decreasing weights. |
