Abstract

For each α>0 \alpha > 0 , the α\alpha-Bloch space is consisting of all analytic functions ff on the unit disk satisfying supz<1(1z2)αf(z)<+. \sup_{|z|<1} (1-|z|^2)^\alpha |f'(z)| < + \infty. In this paper, we consider the following complex integral operator, namely the β\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 α\alpha-Bloch space to itself, where f(0)=0f(0)=0 and βR\beta\in\mathbb{R}. We investigate the boundedness and compactness of the β\beta-Ces\`{a}ro operators and their generalization. Also we calculate the essential norm and spectrum of these operators.
