报告摘要：We characterize the compactness of embedding derivatives from  H^p into L^q for 0<p,q<∞.We also characterize the boundedness and compactness of area operators from  H^p into L^q . Some of the tools used in the proof of the one dimensional case are not available in higher dimensions, such as the strong factorization of Hardy spaces. Therefore, we need the theory of tent spaces which was established by Coifman, Mayer and Stein in 1985.
