Abstract
When Ï is an analytic self-map of the unit disk with Denjoy-Wolff point aâD, and Ï(WÏ,Ï)=Ï(a), we give an exact characterization for when WÏ,Ï is normaloid. We also determine the spectral radius, essential spectral radius, and essential norm for a class of non-power-compact composition operators whose symbols have Denjoy-Wolff point in D. When the Denjoy-Wolff point is on âD, we give sufficient conditions for several new classes of normaloid weighted composition operators.
