| Outline of Final Research Achievements |
Many phenomena observed in nature have hierarchical structures. E.coli which is one of bacteria have a simple movement that each individual repeats straight motion and rotation motion alternately. However, when they are cultivated on a nutrient agar, it is well known that a very regular colony pattern is formed in a macroscopic level. From the viewpoint of experiments and numerical simulations of mathematical models, there are so many studies on E.coli motion in a microscopic level and colony patterns in a macroscopic level. But, a relation between a simple microscopic motion of each individual and a regular macroscopic colony pattern is not known. In this research, we revealed the microscopic and macroscopic relation from a mathematical point of view.
