Query: Difference of composition-differentiation operators from Hardy spaces to
  weighted Bergman spaces via harmonic analysis   In this paper, the boundedness and compactness of the difference of
composition-differentiation operators $D_\varphi-D_\psi$ acting from Hardy
spaces $H^p$ to weighted Bergman spaces $A^q_\alpha$ are completely
characterize for all $0<p,q<\infty$.
