Outline of Final Research Achievements

We study the large-time behavior of solutions to the nonlinear dispersive equations.
The biggest contribution is the classification of the global behavior of solutions to the nonlinear Schrodinger equation with linear potential below the first excited energy. As preliminary studies, we consider the delta potential case and obtain the modified scattering and the asymptotic stability of solitons. By using the knowledge obtained in these studies, the above result is obtained.
We also obtained results on modified scattering. We had much more progress than expected. We obtain the modified scattering result for equations with a general homogeneous critical nonlinearity and the classification result for cubic dispersive systems in one space dimension.

Academic Significance and Societal Importance of the Research Achievements

非線形分散型方程式の解の時間大域ダイナミクスの研究において、現在は不安定ソリトンが一つだけ存在する場合が多く扱われているが、本研究では安定ソリトンが存在する場合を扱うことができた。物理的な背景を考えると、安定ソリトンが存在する状況を考察する方が自然である。本研究でこの状況における解析の基本的な結果が得られた。
長距離散乱理論においては、非多項式型の非線形項の解析を発展させることに成功した。また、この研究で得られた3次方程式系の分類によって、系統的に新しい種類の挙動を発見できた。従来の3次方程式系の分類とは少し異なる視点を与えており、今後の他の分散型方程式系の研究にも応用が可能であると期待される。
