Removal of the auxiliary boundedness assumption in the compactness theorem
Let be a weight, let be an analytic symbol, and let be an analytic function. The boundedness-assumption conjecture. The assumption in Theorem 1 that at least one of the following holds can be dropped:
- and either or ;
- .
Removing this assumption would give a complete characterization of compactness for weighted composition operators such as on weighted BMOA spaces with admissible weights.
