Research Abstract

(1)Jean-Paul Brasselet(ルミニー数学研究所、フランス)とJoerg Schuermann(ミュンスター大学、ドイツ)との共同研究で証明した「Hirzebruch特性類の理論」が、オイラー標数のGrothendieck-Riemann-Roch型定理の拡張として、極めて自然であることを示した。
(2)Levine-Morelのalgebraic cobordismはbordism理論あるいはcobordism理論を基礎に構成されたもので、一般cohomology論の中で普遍的なものである。本研究では、同様な視点から、Fulton-Macphersonのbivariant theoryの意味でuniversal oriented bivariant theoryを構成した。さらに、より幾何学的なuniversal oriented bivariant theoryは現在考察中である。
(3)このuniversal oriented bivariant theoryの構成を切って掛けに、位相幾何学あるいは代数的位相幾何学でよく知られるAtiyahのbordism理論やThomのcobordism理論のbivariant theory版とも言えるbivariant bordism理論を構成した。Daniell Quillenのcobordism理論の構成の関係を現在さらに研究している。
(4)基本的に重要な3つの特性類を統一した、上記のBrasselet-Schurmnn-Yokuraの「Hirzebruch特性類の理論」のゼータ関数の構成に繋がる足がかりして、一般の圏と自然変換に関するゼータ関数を構成する事を考察した。これは、色々な幾何学的指数に付随するゼータ関数の一般化になると思われる。
