Extended Ces $a ˊ$ RO Operators on Zygmund Spaces in the Unit Ball

Zhong-Shan Fang, Ze-Hua Zhou

Let $g$ be a holomorphic function of the unit ball $B$ in the $n$ -dimensional space, and denote by $T_{g}$ and $I_{g}$ the induced extended Ces $a ˊ$ ro operator and another integr…

Composition operators in the Lipschitz Space of the Polydiscs

Zhongshan Fang, Zehua Zhou

In 1987, Shapiro shew that composition operator induced by symbol $ϕ$ is compact on the Lipschltz space if and only if the infinity norm of $ϕ$ is less than 1 by a spectral-theoret…

Essential Norms of Weighted Composition Operators between Hardy Spaces in the unit Ball

Zhong-Shan Fang, Ze-Hua Zhou

Let $ϕ (z) = (ϕ_{1} (z), ..., ϕ_{n} (z))$ be a holomorphic self-map of $B_{n}$ and $ψ (z)$ a holomorphic function on $B_{n}$ , and $H (B_{n})$ the class of all holomorphic functions on $B_{n}$ , where $B…

Difference of composition operators in the Polydiscs

Zhongshan Fang, Zehua Zhou

This paper gives some simple estimates of the essential norm for the difference of composition operators induced by $ϕ$ and $ψ$ acting on bounded function space in the unit polydis…

Compact differences of composition operators from Bloch space to bounded holomorphic function space in the Polydisc

Zhong-Shan Fang, Ze-Hua Zhou

Let $ϕ$ and $ψ$ be holomorphic self-maps of the unit polydisc $U^{n}$ in the $n$ -dimensional complex space, and denote by $C_{ϕ}$ and $C_{ψ}$ the induced composition operators. This pape…
