| 摘 要： | 设T_Ω是带粗糙核的Calderón-Zygmund奇异积分算子,I为任意真包含在单位圆周S~1上的闭圆弧.本文证明,若Ω支在I上并在I上单调,那么T_Ω是从Hardy空间H~1(R~2)到L~1(R~2)的有界算子当且仅当‖Ω‖_(LlogL(S~1))∞.

| Abstract: | Assume TΩ is the Calderón-Zygmund singular integral operator with rough kernel and I is the closed arc of unit circle that I ? S1. In this paper, we prove that if Ω is supported in I and monotonous on I, then TΩ is bounded from Hardy space H1(R2) to L1(R2) if and only if||Ω||L log L < ∞. |
