Boundedness from Below of Composition Operators on <i>α</i>-Bloch Spaces
Abstract We give a necessary and sufficient condition for a composition operator on an α -Bloch space with α ≥ 1 to be bounded below. This extends a known result for the Bloch space due to P. Ghatage, J. Yan, D. Zheng, and H. Chen.
