Outline of Research at the Start

石鹸膜などが重なり合っている状態の動力学の確立を目標とする。界面上では、表面張力、粘着力などがリーディングフォースとなる。また、ジャンクションなど界面が接触している部分の境目で支配ルールが劇的に変化する「自由境界」が出現する(波動型自由境界問題)。これらの動力学を変分法を基本思想に数理解析、数値解析方法の開発を行う。
これらは、微小な液滴やジャンクションを持つ泡などを対象にしており、応用は広いと考えられる。また、変分に基づくため、ラグランジュ乗数などを時間依存形式で導入できる。

Outline of Final Research Achievements

We have established mathematical and numerical treatment of mean curvature acceleration flow. Moreover, we have established multi-bubble kinetics with free boundary. In this case, bubble touch each other and we call bubble intersection 'junction'. Our method also cavers volume constraint phenomena which we need to treat non-local equations.These methods are based on variational treatment of time semi-discretized functional. By this, we have established standard method to treat hyperbolic free boundary problems.

Academic Significance and Societal Importance of the Research Achievements

平均曲率加速度流に対する数学的、数値解析的方法論を確立した。これは水面に接触する石鹸膜の運動を記述する。スカラー関数の場合には、数学的定理をいくつか得た。また、多重泡の動力学が扱えるよう、ジャンクションを持つ泡の数値解析的扱いも確立した。
これらの結果は、双曲型自由境界問題や大域問題に画期的な方法論を提起している。
