Research Abstract

Schrodinger作用素の固有値問題
-Δu(x)+V(x)u(x)=λu(x) λ>0
を考える.Neumann-Wignerの例によれば
V(x)=-k(sin2r)/r+O(r^<-2>) as r=|x|→∞
という形のポテンシャルでλ=1を固有値とするものが存在することが知られている.荒井正治氏(立命館大学)との共同研究により,λ>0が固有値になることと,実定数kの大きさとは関連するということがかなり詳しく分かってきた.
また最近,正の固有値を複数個持つようなポテンシャルの構成にも成功した.
科学研究費補助金は主として
1 関連部門の研究集会等への参加
2 関連部門の研究者との研究連絡・研究打ち合わせ
等の費用として用いられた.またその一部はコンピュータ関連の消耗品購入に当てられた.
