摘要：

A composition operator T(b)f = f o b is completely continuous on H-1 if and only if \b\ < 1 a.e. If the adjoint operator T(b)* is completely continuous on VMOA, then T(b) is completely continuous on H-1. Examples are given to show that the converse fails in general. Two results are given concerning the relationship between the complete continuity of an operator and of its adjoint in the presence of certain separability conditions on the underlying Banach space.
