1 IntroductionLgt b E BMO(Rn) and 11 be a fractional integration with 0 < I < n. The commutator[b, II] generated by b and 11 is defined by[b, II]f(x) = b(x)llf(x) ~ II(sf)(x).S.Chanillolz] stated that the operator [b, II] is a bounded operator from LPI (R") on LPZ(R")for 1/Pz = 1/pl -- l/n and 1 < pl < n/l. Recently, Lu Shanzhen and Yang Dachun[9] studiedthe commutator [b,ll] on Herz spaces and a new class of Herz-type Hardy spaces introducedby them and established the correspondi… 相似文献

Shimo Wang & Dunyan Yan 《分析论及其应用》2012,28(1):79-86
In this paper,we establish two weighted integral inequalities for commutators of fractional Hardy operators with Besov-Lipschitz functions.The main result is that this kind of commutator,denoted by Hb α,is bounded from L x γp (R +) to Lx δ q (R +) with the bound explicitly worked out. 相似文献

It is proved that, for the nondivergence elliptic equations ∑in, j=1 aijuxixj = f,if f belongs to the generalized Morrey spaces Lp,ψ(ω), then uxixj ∈ Lp,ψ(ω), where u is the W2,p-solution of the equations. In order to obtain this, the author first establish the weighted boundedness for the commutators of some singular integral operators on Lp,ψ (ω). 相似文献

Let D be the unit disc and H(D) be the set of all analytic functions on D. In [2], C. Cowen defined a space H = f ∈ H(D) : f(z) =sum from k=o to ∞ ak(z + 1)k, z∈ D, ‖f‖2 = sum from k=o to ∞ |ak|24k < ∞In this article, the authors consider the similar Hardy spaces with arbitrary weights and discuss some properties of them. Boundedness and compactness of composition operators between such spaces are also studied. 相似文献

For 0 < α < mn and nonnegativeintegers n ≥ 2,m ≥ 1, the multilinear fractional integral is defined by Iα(m )(→f )(x) = ∫(Rn)m 1/ ︱→y |mn-α m ∏ i=1 fi(x-yi)d→y , where →y = (y1,y2,··· ,ym) and →f denotes the m-tuple (f1, f2,··· , fm). In this note, the one-weighted and two-weighted boundednesson Lp(Rn) space for multilinear fractional integral operator Iα(m )and the fractional multi-sublinear maximal operator Mα(m )are established re-spectively. The authors also obtain two-weighted weak type estimate for the... 相似文献
