Composition operators from \(\mathcal{B}^{\alpha}\) to \(Q_K\) type spaces (Q949086)

The author presents necessary and sufficient conditions for the continuity or compactness of composition operators \(C_\phi\) from an \(\alpha\) Bloch space, \(\alpha>0\), or from the space of analytic functions on the disc with bounded derivative, into a \(Q_K\) type space for a non-negative, non-increasing function \(K(r)\) on \(]0,\infty[\) with other natural properties.
