摘要: 该文讨论了$\a$-Bloch空间$\ba$和对数Bloch空间$\bl$之间的加权Ces\'aro
算子$\tg$的有界性和紧性,给出$\tg$是$\ba$到$\bl$的有界算子或紧算子的充要条件和$\tg$是$\bl$到$\ba$的有界算子或紧算子的充要条件.

关键词: 加权Ces\''aro算子, 权Bloch 空间, 有界算子, 紧算子

Abstract: In this paper the extendedCes\'aro operator $\tg$ is characterized between the $\a$-Bloch spaces $\ba$ and the logarithmic weighted Bloch space $\bl$ on the unit disc. Some necessary and sufficient conditions are given for $\tg$ to be a bounded operator or a compact operator from $\bl(\ba)$ to $\ba(\bl)$.

Key words: Extended Cesàro operators, Weighted Bloch spaces, Bounded operator, Compact operator
