Query: Commutators of weighted Hardy operator on weighted $\lambda$-central
  Morrey space   In this paper, the authors prove the boundedness of commutators generated by
the weighted Hardy operator on weighted $\lambda$-central Morrey space with the
weight $\omega$ satisfying the doubling condition. Moreover, the authors give
the characterization for the weighted $\lambda$-central Campanato space by
introducing a new kind of operator which is related to the commutator of
weighted Hardy operator.
