| Abstract： |
Let n>1 and B be the unit ball in n dimensions complex space bf C^{n}. Suppose that \varphi is a holomorphic self-map of B and \psi\in H(B) with \psi(0)=0. A kind of integral operator, composition Ces\`{a}ro operator, is defined by T_{\varphi,\psi}(f)(z)=\int_{0}^{1}f[\varphi(tz)]R\psi(tz)\frac{\rmd t}{t}, \quad f\in H(B), \ z\in B.
In this paper, the authors characterize the conditions that the composition Ces\`{a}ro operator T_{\varphi, \psi} is bounded or compact on the normal weight Zygmund space \mathcal{Z}_{\mu}(B). At the same time, the sufficient and necessary conditions for all cases are given. |
