在這計畫中，我們將用各種極大函數、Littlewood-Paley 平方函數、Lusin面積積分 及Riesz變換來刻畫 ag Hardy spaces H1F (RnXRm)。 ;In this project, we extend the classical characterization of Hardy spaces via maximal functions, the Littlewood-Paley square function, Lusin area integrals and the Riesz trans- forms to the setting of the ag Hardy spaces H1F (RnXRm).
