报告摘要：We present recent results on the existence of traveling wave solutions for a chemotaxis model of cells and a chemical signal with nonlinear chemical gradient. We first discuss rather  complete existence results when  the diffusion coefficient of the cells is small and then the general case without this restriction. We outline their proofs that rely on the theory of the geometric singular perturbations, phase space analysis, LaSalle’s invariant principle, etc.
