报告摘要:The theory of Hardy spaces over $\mathbb R^n$, originated by C.Feffermanand Stein, was generalized several decades ago to the case of subsets of $\mathbb R^n$. The pioneering work of generalization was done by Jonsson, j\"ogren, and Wallin for the case of suitable closed subsets and by Miyachi for the case ofproper open subsets.In this article we study Hardy spaces on proper open $\Omega\subset \Bbb R^n$, where $\Omega$ satisfies a doubling condition and $|\Omega|=\infty$.We first establish a variant of the Calder\'on-Zygmund decomposition, and then explore the relationship among Hardy spacesby means of atomic decomposition, radial maximal function, and grand maximal function.
