报告摘要 Abstract:
Whether chemotaxis collapse phenomenon will occur for Keller-Segel model with signal consumption has always been a subject of great concern to mathematicians. This talk is concerned with the finite time blow-up phenomenon of solutions of Keller-Segel model with signal consumption and singular sensitivity. We study this problem by using backward self-similar solution. Through detailed structural analysis, we gain clear insights into the behavior of the self-similar profiles.
