报告摘要: There are two kinds of Keller-Segel models in chemotaxis: one is the so-called chemotaxis-production model where the chemical signal is produced by the organism; the other is the so-called chemotaxis-consumption model where the chemical is consumed by the organism. In this talk, I will first review the existence and stability of spiky steady states to the both models, and then introduce my contributions with collaborators in this direction.
