报告摘要：

In this talk, we present our results on the dynamical stability of nonconstant stationary solutions to the chemotaxis models that describes the concentration phenomena of bacteria consuming oxygen. In mathematics, the phenomena can be represented by traveling band or spiky steady states. In this talk, we mainly focus on the spiky steady states on the bounded domain or half space. We mention that the key mechanics to generate spike profiles for this chemotaxis mode1 of consunption type is the presence of nonhomogeneous boundary conditions.
