TITLEKeller-Segel Equations with Nonlinear Interactions and Small Diffusions

ABSTRACT In this talk, we consider the one-dimensional Keller-Segel equations with small diffusion and nonlinear interaction between cells and chemical signals. We study the existence of the traveling pulses by the geometric singular perturbations and the trapping region. We show such traveling pulse is unstable by the spectral analysis.
