The Hilbert matrix operator into the Bergman space

Abstract

We prove that the Hilbert matrix operator $H:A^2_{\ln^{\alpha}} \to A^2$ is bounded when $\alpha\geq 2$ and that $H$ does not map $A^2_{\ln^{\alpha}} $ into $A^2$ when $\alpha<2$, solving an open problem posed by B. Karapetrovi\'c and M. Jevti\'c. The boundedness when $\alpha=2$ is shown as a corollary to the more general statement: the Hilbert matrix $H:\ell_v^p \to \ell_w^p$ is bounded, where $v(n) = (\ln n)^p / n$ and $w(n) = 1/n$.
