Reverse Carleson measures for spaces of analytic functions (2412.02354v1)
Abstract: Let $X$ be a quasi-Banach space of analytic functions in the unit disc and let $q>0$. A finite positive Borel measure $\mu$ in the closed unit disc $\overline{\mathbb{D}}$ is called a $q$-reverse Carleson measure for $X$ if and only if there exists a constant $C>0$ such that $$|f|{X}\leq C |f|{Lq(\overline{\mathbb D},d\mu)} $$ for all $f\in X\cap C(\overline{\mathbb D})$. We fully characterize the $q$-reverse Carleson measures with all $q>0$ for Hardy spaces $Hp(\mathbb D)$ with all $0<p\leq \infty$, for the space $\mathrm{BMOA}(\mathbb D)$ and for the Bloch space. In addition, we describe $q$-reverse Carleson measures for the holomorphic Triebel--Lizorkin spaces $HF_0{q,r}$ and the holomorphic Besov spaces $HB_0{q,r}$. Related results are obtained for the Hardy spaces and certain holomorphic Triebel--Lizorkin spaces in the unit ball of $\mathbb{C}d$.
