摘要
本文证明了分数次Hardy算子广义交换子是Herz型Hardy空间到Herz空间有界的,当且仅当交换子为零算子.因此,本文用了一个弱型估计代替,即交换子由Herz型Hardy空间到弱Herz空间有界.
In this paper, we prove that the generalized commutator of fractional Hardy operator HΩ^m,A,β is not bounded from HKq1^n(1-1/q1),p (R^n) to Kq2^n(1-1/q1),p(R^n) unless HΩ^m,A,β≡0. Therefore, we prove a weak estimate instead, that is, HΩ^m,A,β is bounded from HKq1^n(1-1/q1),p (R^n) to WKq2^n(1-1/q1),p (R^n).
