Outline of Final Research Achievements

In this project we are concerned with various wave propagetion phenomena of Schr"odinger and Klein-Gordon evolution equations. The central object is in the smoothing and Strichartz estimates for magnetic Klein-Gordon equations in exterior domain. Results are obtained sccessfully and are applied to analyze some scattering problems. Note that our Strichartz estimates, in three or more dimensional cases, require energy loss which seems unnecessarily high. There may remain a room we sholud make clear.
As for the 1 dimensional Shr"odinger operators, the inverse problem to determine the potential from scattering matrix is studied on several infinite graphs containing loop, which partly make progress our formar results for star-shaped infinite graphs. Main parts of our new results are restricted to the uniqueness and stability of solutions.

Academic Significance and Societal Importance of the Research Achievements

本研究は物理学の基礎方程式を対象にして、その解の時空での挙動を解析する。物理学の成果を跡付けしているとも言えるが、確立された数学が物理学を含む他分野の未来の発展に寄与することは疑えないことであろう。
解析学は他分野と距離が近く、例えばグラフ上の量子力学はナノテクノロジーや量子コンピュータの回路設計などに応用される。しかし、この研究は直接応用を意識するものはでなく、解析学の諸分野の交差する問題意識の一部でも整理し、統一的な理論の発展を願ってなされている。
