应西北师范大学数学与统计学院邀请，广西民族大学刘振海教授将为我院师生作线上学术报告。
报告题目：Differential Variational Inequalities and their applications
报告摘要：In this talk, we consider a differential system obtained by mixing an evolution differential equation and a variational inequality. This kind of problems may be regarded as a special feedback control problem. Firstly, we give our research motivation and examples. Then, based on the theory of semigroups, Filippov implicit function lemma and fixed point theory for set-valued mappings, we show several existence results of solutions to the mentioned problem. Finally we point out some problems for the further research.
