AB - <p>When $\varphi$ and $\psi$ are holomorphic self-maps of the unit disk with bounded multiplicity, we give a compact characterization for the difference of composition operators $C_\varphi $ and $C_\psi $ acting on the Hardy space, which extends a recent result in the case of univalent maps by Choe et al.</p>
