Outline of Final Research Achievements

On the mathematical model of non-local tumour invasion proposed by M.Chaplain et al. we give an appropriate mathematical framework, then obtain a mathematical characterization of the non-local term. Based on it we can show the global existence in time and the asymptotic behaviour of the solution to the model. We found the non-local term is not well-defined on the boundary between the domain of the definition of the non-local term and others. Finally Chaplain admitted this point and added a modification to the term with a biological justification. By making use of it we extend the domain of the definition of the term to the whole space and we understand the term mathematically as a kind of a generalized differential operator, for example, the singular integral operator or others. Then we can derive energy estimates of the model, which enables us to obtain the desired results, and guarantee the validity and mathematical justification of the model.

Academic Significance and Societal Importance of the Research Achievements

がんや腫瘍の特定と治療は早急に克服すべき人類最大の課題の一つである。そのため腫瘍の発現や発達のメカニズムの解明は急務であろう。しかしこれらの多くは数学的に新しい問題を内在しているが、その数理モデルの導出原理や方程式の理論解析が十分とはいえない。本課題研究では生命科学で重要な研究対象である「腫瘍」の数理モデルの数学解析と医学への応用について研究する。そのため十分な説得力をもつ非局所腫瘍浸潤モデルを取り上げ、適切な数学的枠組みを与え、滑らかな時間大域解の存在とその漸近挙動を示した。これはモデルとシミュレーションの妥当性を保証し、測定不可能な腫瘍侵潤部分、進行速度の特定など医学への貢献が期待される。
