Outline of Final Research Achievements

We constructed discrete models for some deformations of curves in plane and in space. In particular, from the viewpoint of integrable systems, an integrable discrete model of the local induction equation, which is known as a mathematical model of vortex filaments, is formulated to construct a family of characteristic exact solutions. From the viewpoint of non-integrable systems, a simple discrete model of the curve shortening flow is proposed.

Academic Significance and Societal Importance of the Research Achievements

離散的な図形の性質と構成方法を研究した。本研究では例えば曲率に相当するような離散的概念を見出すことを通して離散的図形をコントロールしたため、構成した図形は汎用的な離散化アルゴリズムで生成したものに比べてよい特性を持っている。具体的には特に渦糸の運動に対する可積分離散モデルを作り、特徴的な厳密解の族を構成した。このモデルを雛形のひとつとして今後さらに離散的図形の幾何学が進展することが期待できる。
