| 摘 要： | The singular integral operator J Ω,α, and the Marcinkiewicz integral operator (~μ)Ω,α are studied. The kernels of the operators behave like |y|-n-α(α＞0) near the origin, and contain an oscillating factor ei|y|-β(β＞0) and a distribution Ω on the unit sphere Sn-1 It is proved that, if Ω is in the Hardy space Hr (Sn-1) with 0＜r= (n-1)/(n-1 )(＞0), and satisfies certain cancellation condition,then J Ω,α and uΩ,α extend the bounded operator from Sobolev space Lpγ to Lebesgue space Lp for some p. The result improves and extends some known results.

| Abstract: | The singular integral operator J
Ω,α
, and the Marcinkiewicz integral operator
are studied. The kernels of the operators behave like |y|-n-α(a>0) near the origin, and contain an oscillating factor ei|y|-β (β>0) and a distribution ω on the unit sphere S
n−1. It is proved that, if ω is in the Hardy space H
r
(S
n−1) with 0<r=(n−1)/(n−1+γ)(γ>0), and satisfies certain cancellation condition, then T
Ω,α
and
extend the bounded operator from Sobolev space L
γ
ρ
to Lebesgue space L
p
for some p. The result improves and extends some known results. |
