要旨: | Self-organized pattern formation of run-and-tumble chemotactic bacteria is investigated based on a mesoscopic kinetic chemotaxis model, in which a kinetic transport equation for chemotactic bacteria is coupled with a reaction-diffusion equation for chemical cues. The instability analysis of the kinetic chemotaxis model [1] and the traveling wave analysis of the related flux-limited Keller-Segel system [2] are introduced in this talk. The special focus is put on the multiscale mechanism between the macroscopic pattern formation and individual motions of chemotactic bacteria with stiff response.
