Abstract  Suppose that $\alpha>1$. Let $u$ be analytic in the unit disc $D$ and $\varphi$ be analytic map-self on $D$. In the paper, the authors give the simple necessary and sufficient condition of the weighted composition operator $uC_{\varphi}$ being compact from $\beta_{L}$ to $\beta_{\alpha}$ on $D$.

单位圆上对数权Bloch型空间复合型算子紧性条件的一种改进

设$\alpha>1$, $u$在单位圆$D$内解析, $\varphi$是$D$上的解析自映射. 本文给出了$D$中从$\beta_{L}$到$\beta_{\alpha}$的加权复合算子$uC_{\varphi}$为紧算子的简捷充要条件.
