在这份报纸,这被证明整流器 H ,被n维的部分强壮的操作员 H 产生的 b 和 b ()( Rn )是从 LP ( Rn )的 hounded 到 Lq ( Rn ) 0 << 1 , 1 < p , q <并且嘴唇- 1/q =(+) /n 。而且, H 的固定,同质的 Herz 空间(K) 上的 b, pq (Rn ) 被获得。
In this paper, it is proved that the commutator Hβ,b which is generated by the n-dimensional fractional Hardy operator Hβ and b ∈λα (R^n) is bounded from L^p(R^n) to L^q(R^n), where 0 〈 α 〈 1, 1 〈 p, q 〈 ∞ and 1/P - 1/q = (α+β)/n. Furthermore, the boundedness of Hβ,b on the homogenous Herz space Kq^α,p(R^n) is obtained.
