Research Abstract

研究分担者, 連携研究者の協力の下, リジッド幾何学の基礎付けを研究した. 特に, EGA III より一般の枠組みで形式幾何学を展開している. 基礎付けの応用としてスキームおよび代数空間の永田コンパクト化の構成など, 代数幾何学での基本的な定理がある. また, 可換環の完備化の理論の(非ネーター環を含む)再構成等でも新たな見方を提示しており, 形式スキームとしてのネーター性がなくてもリジッド空間としてのネーター性があれば 十分であることを発見した. これは特にR. Huber によるadic space の理論が成立する枠組みを明快にするものである.基礎付け一般の結果は加藤文元(京都)との共著として発刊する予定である.
