Teachers Zhang Xu, Wang Xiaoqiang, Zhang Yusen, Zhou Li, Hu Qinqin, Gao Zhiqiang, Ye Yinna, Fan Xiequan and graduate students of our school attended this report online.

In this talk, Professor Liu introduced the basic concepts of large deviations, related theories and applications in branching random walks at the beginning . Then he mainly presented his milestone results about large deviations for products of random matrices, which have numerous applications in a variety of problems in pure and applied probability. At last, he had an in-depth discussion on the related issues in this talk with teachers and students, explained the questions raised by participants, and shared the further research in the field of large deviations. In addition, Professor Liu also enthusiastically introduced Universitéde Bretagne-Sud, and how to apply for scholarships for students.
