RESEARCH ANNOUNCEMENTS Rough Marcinkiewicz Integrals With L（log＋L）^2 Kernels on Product Spaces

Let Rv (N>2,N＝n or m)be the N-dimensional Euclidean space and SN-1 be the unit sphere in Rv.For nonzero point x E RN,we denote x＇＝x/|x|. E.M.Stein[12]defined a high dimensional analogue of the Marcinkiewicz integral on Rn byμΩ(f)(x)＝(∫n|Fs(x)|2 ds)1/2,where Ωis a homogeneous function of degree zero, whose restriction to Sn-1 is in L1(Sn-1) and satisfies the cancellation property ∫sn-1Ω(x＇)dx＇＝0.It is well-known that the Marcinkiewicz integral is very useful in harmonic analysis. Readers can see [1, 2, 5, 7, 9-13],among numerous references,for its development and applications.

L p -Boundedness of Marcinkiewicz Integrals with Hardy Space Function Kernels

We give the L ^p -boundedness for a class of Marcinkiewicz integral operators μ_Ω, μ^ast; _{Ω, λ} and μ_Ω, _s related to the Littlewood-Paley g-function, g ^* _λ-function and the area integral S, respectively. These operators have the kernel functions Ω∈H ¹ (S ⁿ⁻¹), the Hardy space on S ⁿ⁻¹. These results in this paper substantially improve and extend the known results.
