报告摘要：In this talk, we shall show the $L^2$-boundedness for the jump functions and variations of Calder\'on-Zygmund singular integral operators. This result should be the first general criteria for the variational inequalities for kernels not necessarily of convolution type. The $L^2$-boundedness assumption that we verified here is also the starting point of the related results on the (sharp) weighted norm inequalities appeared in many recent papers.
