摘 要: | 证明了参数型Marcinkiewicz积分μΩ^p是(H^p,∞ , L^p,∞)(0〈p≤1)型的算子,这里Ω是满足Lipα条件的R^*上的零次齐次函数.对于p=1,减弱了Ω的条件μΩ^p得到μΩ^p是(H^1,∞ , L^1,∞)型的.作为上述结果的推论,得到了μΩ^p是弱(1,1)型的算子.

Abstract: | we prove that the parametric Marcinkiewicz integral μΩ^p is an operator of type (H^p,∞ , L^p,∞ ) (0〈p≤1), if Ω∈ Lip, is a homogeneous function of degree zero. For p= 1, we weaken the smoothness condition assumed on Ω and again obtain μΩ^p is of type (H^1,∞ ,L^1,∞ ). As a corollary of the results above, we give the weak type (1,1) boundedness of μΩ^ρ. |
