报告摘要:Keller-Segel system is a classical model describing chemotaxis. In dimension two, its solutions may blow up in finite time, which is caused by mass concentration. In this talk I will discuss a blow up analysis theory for this concentration phenomena. This is the first step to understand the classification of blow up mechanism in the Keller-Segel system. Based on a joint work with Chen Hua and Li Jian-Meng.
