报告题目：Weighted norm inequalities for singular integral operators controlled by different norms
报告摘要：To characterize composition operators arising in study of $\bar{\partial}$-Neumann problem, Nagel, Ricci, Stein and Wainger introduced and studied two classes of kernels $P(E)$ and $P_0(E)$, and studied their $L^p,1<p<\infty$ regularity properties. We introduce a new maximal function associated with a sub-collection of product rectangles. This maximal function is used to obtain precise control on the kernels in $P(E)$ and $P_0(E)$ and to build the new class of weights in this multiparameter situation. Weighted Hardy and local Hardy spaces are then introduced and boundedness of convolution operators with $P_0(E)$- and $P(E)$-kernels are derived in these spaces. Applications to product kernels of Phong-Stein type are presented. This is based on joint work with Lei Ji, Der-Chen Chang, Yongsheng Han, and Dunyan Yan.
