Stability of admissible functions
Summary: Using the concept of weak subordination we examine stability for a class of admissible functions in complex Banach spaces. (A class of analytic functions in the unit disk is said to be stable if it is closed under weak subordination.) Following classes are discussed: the Bloch class, the little Bloch class, the hyperbolic little Bloch class, the extended Bloch class (\(Q_p\)), and the Hilbert Hardy class (\(H^2\)).
