讲座摘要：

In this talk, I shall present some progresses on variational estimates of vector-valued averaging operators, of vector-valued Hilbert transform, bilinear averaging operators etc, and try to explain why variational inequalities are interesting and are required to be completely understood in harmonic analysis. This is based on joint works with Yanping Chen, Yong Ding, Danqing He, Wei Liu, Honghai Liu，Tao Ma， Xinfeng Wu and Jie Xiao.
