中文摘要:
      设μ是一个正规函数,P>0.分别刻画了Cn中单位球上μ-Bergman空间Ap(μ)上复合算子Cψ为有界算子以及紧算子时,ψ所满足的充要条件,同时给出了P>1时Cψ为AP(μ)上紧算子的简化充分条件和必要条件.
英文摘要:
      Let $\mu$ be a normal function, and $C_{\varphi}$ be the composition operator. The authors characterize those $\varphi$ for $C_{\varphi}$ is bounded (or compact) on the $\mu$-Bergman space $A^{p}(\mu)$ in the unit ball of $C^{n}$.
