Based on the theory of variable exponents and BMO norms,we prove the vector-valued inequalities for commutators of singular integrals on both homogeneous and inhomogeneons Herz spaces where the two main indices are variable exponents.Furthermore,we show that a wide class of commutators generated by BMO functions and sublinear operators satisfy vector-valued inequalities. 相似文献

Suppose b =(b_1, ···, b_m) ∈(BMO)~m, I_(α,m)~(Πb) is the iterated commutator of b and the m-linear multilinear fractional integral operator I_(α,m). The purpose of this paper is to discuss the boundedness properties of I_(α,m) and I_(α,m)~(Πb) on generalized Herz spaces with general Muckenhoupt weights. 相似文献

The generalized Morrey spaces are introduced under the hypothesis that Rn is endowed with the general parabolic metric , and the boundedness properties are established in generalized Morrey spaces for a class of singular integral operators, which include Calderon-Zygmund singular integrals and their commutators with BMO. 相似文献

In order to study the boundedness of some operators in general function spaces which include Lorentz spaces and Orlicz spaces as special examples,Lorentz introduced a new space called rearrangement invariant Banach function spaces,denoted by RIBFS.It is shown in this paper that variation operators of singular integrals and their commutators are bounded on RIBFS whenever the kernels satisfy the Lr-H?rmander conditions.Moreover,we obtain some quantitative weighted bounds in the quasi-Ba... 相似文献

In this paper,the authors introduce certain Herz type Hardy spaces with variable exponents and establish the characterizations of these spaces in terms of atomic and molecular decompositions. Using these decompositions,the authors obtain the boundedness of some singular integral operators on the Herz type Hardy spaces with variable exponents. 相似文献

The final aim of this work is to prove the Central Limit Theorem described in the motivations given below. The key for that is a Resolvant estimate, of the type of Theorem 1.1 in [21], adapted for the Parabolic Green function G(X, Y) which is the heat diffusion kernel in some domain Ω in time-space: i.e. we must estimate ${\int_{\Omega}\nabla_{Y}G(X, Y)\nabla_{Y}^{2}G(Y,Z)\;dY}The final aim of this work is to prove the Central Limit Theorem described in the motivations given below. The key for that
is a Resolvant estimate, of the type of Theorem 1.1 in [21], adapted for the Parabolic Green function G(X, Y) which is the heat diffusion kernel in some domain Ω in time-space: i.e. we must estimate òW?YG(X, Y)?Y2G(Y,Z) dY{\int_{\Omega}\nabla_{Y}G(X, Y)\nabla_{Y}^{2}G(Y,Z)\;dY}. Exactly as the estimate in [21] is based on [10] our estimate here is based on the main Theorem of this paper. This main
theorem refers to rough singular integrals on the Gaussian potential on ∂Ω. 相似文献

Let E be a subset in (n+1)-dimensional Euclidean space with parabolic homogeneity, codimension 1, and with an appropriate surface measure σ associated with it. For certain kinds of parabolic Calderón–Zygmund operators T we prove that the L 2(E,dσ)-boundedness of T is equivalent to the parabolic uniform rectifiability of E. This is a parabolic version of a well-known result of G. David and S. Semmes. 相似文献

The Commutators of Fractional Integrals on Besov Spaces 总被引:1,自引:0,他引:1
Abstract
In this paper we consider the commutators of fractional integrals
on the Besov spaces
, where b is a locally integrable function and 0 < α < n. We first establish the equivalence between the boundedness of the commutators
and the paraproduct of J. M. Bony. Then we obtain two conditions on the boundedness of the commutators. One of these conditions
is necessary and the other is sufficient.

C. Herz introduced in [Hr] some new spaces to study properties of functions. An Interesting account, with many applications, of some particular cases of the generalized Herz spaces is given in [BS]. In this paper we first identify the duals of the generalized Herz spaces. Then, we characterize their intermediate spaces when the complex method of interpolation for families of spaces Is used. Applications are given that show the bounded ness of many operators on the generalized Herz spaces. 相似文献
