The multi-parameter Hausdorff operators on H^1 and L^p
In the present paper, we characterize the nonnegative functions ϕ for which the multiparameter Hausdorff operator H ϕ generated by ϕ is bounded on either the multi-parameter Hardy spaceThe corresponding operator norms are also obtained.Our results improve some recent results in [4,15,16,18] and give an answer to an open question …
