| Outline of Final Research Achievements |
We carried out numerical and theoretical studies on the traveling wave and aggregation of bacteria, which are fundamental problems in the cluster formation dynamics, based on a kinetic chemotaxis model.
In the traveling wave problem, we theoretically obtained a dispersion relation of the population traveling wave of bacteria and numerically uncovered the variety of traveling wave solutions. In the aggregation problem, we theoretically obtained a linear instability condition, under which the bacteria create patterns from a uniform constant state. We also developed a new mesoscopic simulation method, i.e., a Monte Carlo simulation for chemotactic bacteria. The accuracy and validity of the Monte Carlo method has been established throughout comparisons of theoretical and experimental results.
This study fundamentally contributes to establishing a new academic research field, i.e., the study of active fluids.
