Traveling wave (band) behavior driven by chemotaxis was observed experimentally by Adler1,2and was modeled by Keller and Segel.15For a quasilinear hyperbolicparabolic system that arises as a non-diffusive limit of the KellerSegel model with nonlinear kinetics, we establish the existence and nonlinear stability of traveling wave solutions with large amplitudes. The numerical simulations are performed to show the stability of the traveling waves under various perturbations.
