Abstract
Let $ mathcal{H}(mathbb{D}) $ denote the space of analytic functions on the open unit disc $mathbb{D}$. For a weight $mu$ and a nonnegative integer $n$, the $n$'th weighted type space $ mathcal{W}_mu ^{(n)} $ is the space of all $fin mathcal{H}(mathbb{D}) $ such that $sup_{zin mathbb{D}}mu(z)left|f^{(n)}(z)right|
设$mathcal{H}(mathbb{D})$表示开单位圆盘$mathbb{D}$上解析函数的空间。对于权重$mu$和非负整数$n$,第$n$个加权类型空间$mathcal{W}_mu^{(n)}$是所有$fin-mathcal{H}(mathbb{D}赋以范数开始{align*}left |f right |_{mathcal{W}_mu^{(n)}}=sum_{j=0}^{n-1}left|f^{(j)}(0)右|+sup_{zin-mathbb{D}}mu(z)左|f^{(n)}(z)右|,end{align*}第$n$个加权类型空间是Banach空间。在本文中,我们刻画了广义加权复合算子$mathcal的有界性{D}_{varphi,u}^m$来自对数Bloch类型空间$mathcal{B}_{{log}^beta}}^alpha$到第$n$个加权类型空间$mathcal{W}_mu^{(n)}$,其中$u$和$varphi$是$mathbb{D}$和$varphi(mathbb{D})substeqmathbb{D}$上的分析函数。我们还对这些算子的本质范数进行了估计。
