摘要
让 $\psi \in H(\BB_n),$ $C^n 的单位球 $\BB_n$ 上所有全态函数的空间,$\varphi = (\varphi_1, \ldots, \varphi_n)\in S(\BB_n)$ $ $\BB_n 的全态自映射的集合:\(and $ \mathcal B_{\nu}$) $\to \mathcal B_{\mu} $ (and $ \mathcal B_{\mu,0}$) be weighted extended Ces\`aro operators induced by the products of the extended Ces\`aro operator $ C_\varphi $ and integral operator $T_\psi.在本文中,我们通过对 $ |\varphi| $ 或 $ |\varphi_k| $ 的估计来描述 $ C_{\psi,\varphi} $ 的有界性和紧凑性。$}同时,我们还给出了这些算子规范的渐近估计值。
On the boundedness and compactness of extended Ces\`aro composition operators between weighted Bloch-type spaces
Let $\psi \in H(\BB_n),$ the space of all holomorphic functions on the unit ball $\BB_n$ of $\C^n,$ $\varphi = (\varphi_1, \ldots, \varphi_n) \in S(\BB_n)$ the set of holomorphic self-maps of $\BB_n.$ Let $C_{\psi, \varphi}: \mathcal B_{\nu}$ (and $ \mathcal B_{\nu,0}$) $\to \mathcal B_{\mu} $ (and $ \mathcal B_{\mu,0}$) be weighted extended Ces\`aro operators induced
by products of the extended Ces\`aro operator $ C_\varphi $ and integral operator $T_\psi.$
In this paper, we characterize the boundedness and compactness of $ C_{\psi,\varphi} $ via the estimates for either $ |\varphi| $ or $ |\varphi_k| $ \textit{for some $ k\in \{1,\ldots,n\}. $} At the same time, we also give the asymptotic estimates of the norms of these operators.
