Outline of Final Research Achievements

We studied a parabolic-parabolic chemotaxis system with logistic growth. We showed the global-in-time existence of solutions to the chemotaxis system which has subquadratic degradation and nonlinear secretion. In addition, we showed the bifurcation of nontrivial solutions from the uniform state of the system, which indicates pattern formations, for instance, hexagonal and regular nesting patterns.

Academic Significance and Societal Importance of the Research Achievements

本研究では走化性・増殖系の数理モデルとしての基本的性質の一部を明らかにしました.数理モデルの性質が明らかとなれば,その結果を現象の理解に役立てることができます.数理モデルを研究することの利点には,現象を予測し,さらに制御できる可能性が広がることなどがあります.本研究で扱った数理モデルは,主に大腸菌に対する走化性モデルですが,走化性は菌のみならず,白血球や昆虫などにも存在しており,本研究を含む基礎研究が,様々な自然現象の予測と制御へとつながる可能性があります.
