| contents | Let $0<p<\infty$ and $Ψ: [0,1) \to (0,\infty)$, and let $μ$ be a finite positive Borel measure on the unit disc $\mathbb{D}$ of the complex plane. We define the Lebesgue-Zygmund space $L^p_{μ,Ψ}$ as the space of all measurable functions $f$ on $\mathbb{D}$ such that $\int_{\mathbb{D}}|f(z)|^pΨ(|f(z)|)\,dμ(z)<\infty$. The weighted Bergman-Zygmund space $A^p_{ω,Ψ}$ induced by a weight function $ω$ consists of analytic functions in $L^p_{μ,Ψ}$ with $dμ=ω\,dA$. Let $0<q<p<\infty$ and let $ω$ be radial weight on $\mathbb{D}$ which has certain two-sided doubling properties. In this study, we will characterize the measures $μ$ such that the identity mapping $I: A^p_{ω,Ψ} \to L^q_{μ,Φ}$ is bounded and compact, when we assume $Ψ,Φ$ to be almost monotonic and to satisfy certain doubling properties. In addition, we apply our result to characterize the measures for which the differentiation operator $D^{(n)}: A^p_{ω,Ψ} \to L^q_{μ,Φ}$ is bounded and compact. |
