Composition operators on the weighted BMOA spaces with closed range
Abstract
We study the composition operator Cφ with closed range on the weighted space :Let α > 0. Suppose φ is a univalent self-map of . Then the bounded composition operator is bounded below if and only if φ is an automorphism of the open unit disk .
