Abstract:
In the paper compact multiplier operators $$M_{lambda}: X rightarrow E$$ from Banach spaces of analytic functions on the unit disk into Banach sequence lattices are studied. If $$H_{infty} hookrightarrow X hookrightarrow H_{2}$$, then the characterization of compact multipliers is obtained through calculating the Hausdorff measure of noncompactness of diagonal operators between Banach sequence lattices. Furthermore, in the general case $$H_{infty} hookrightarrow X hookrightarrow H_{1}$$, necessary and sufficient conditions for compactness are presented.
