Abstract

It is well known that the Korenblum maximum principle holds in Bergman spaces \(\mathrm {A}^{p}\) if and only if \(p\ge 1\). In this note, we improve this result by proving that the Korenblum maximum principle holds in mixed norm spaces \(\mathrm {H}^{p,q,\alpha }\) when \(1\le p\le q<\infty \) and does not hold when \(0<q<1\). As an immediate consequence, we obtain that the Korenblum maximum principle holds in weighted Bergman spaces \(\mathrm {A}^{p}_{\gamma }\) if and only if \(p\ge 1\).
