Research Abstract

研究成果の概要 : 複素解析曲面と超ケーラー多様体に見られる著しい類似性に着目することにより、ケーラー多様体の双有理型変換群の粗分類定理(Tits型定理)を確立した。また、分類に現れる非可換自由群および最大階数のアーベル群のラグランジアンファイブレーションを用いた構成法を確立した。また、自己同型の複素力学的意味, ラグランジアンファイブレーションの一般特異ファイバーの分類, 超ケーラー多様体の代数次元、特に4次元の場合の完全な記述を与えた。以上の研究に加えて、滑らかな小変形を有せず、互いに双有理であるが射影平坦変形でつながりしかも同相ではない3次元多様体カラビ・ヤウ多様体の存在を発見した。以上の研究が評価され日本数学会代数学賞を受賞した。
