題  目：Traveling Waves in Chemotaxis Models with Logistic Source

内容簡介：Traveling wave solutions are an important class of solutions in many mathematical models in the fields of population biology, population genetics, material sciences, and physiology. This talk is concerned with traveling wave solutions in chemotaxis models with logistic source. Such models are used to describe the movements of biological species or living organisms in response to certain chemicals in their environments. In particular, I will discuss the existence of traveling wave solutions in such models. Special attention will be given to the combined effect of the chemotaxis sensitivity and the logistic damping on the speed of traveling wave solutions.
