Properties of $β$-Cesàro operators on $α$-Bloch space (1808.08844v2)

Abstract: For each $ \alpha > 0 $, the $\alpha$-Bloch space is consisting of all analytic functions $f$ on the unit disk satisfying $ \sup_{|z|<1} (1-|z|^2)^\alpha |f'(z)| < + \infty.$ In this paper, we consider the following complex integral operator, namely the $\beta$-Ces`{a}ro operator \begin{equation} C_\beta(f)(z)=\int_{0}^{z}\frac{f(w)}{w(1-w)^{\beta}}dw \nonumber \end{equation} and its generalization, acting from the $\alpha$-Bloch space to itself, where $f(0)=0$ and $\beta\in\mathbb{R}$. We investigate the boundedness and compactness of the $\beta$-Ces`{a}ro operators and their generalization. Also we calculate the essential norm and spectrum of these operators.
