Outline of Annual Research Achievements

本研究の目的は、Z被覆状の端を持つ4次元多様体に対してゲージ理論を展開し、それを低次元トポロジーに応用する事であった。特にホモロジーS^1×S^3の不変量の構成も目標としていた。これらに関わり、今年度の研究を次のように述べられる。
・初年度に証明していた埋め込みの障害に関する定理を大幅に拡張した。また、従来の証明は、Z被覆状の端を持つ4次元多様体上でASD方程式の解のモジュライ空間を観察するものであったが、今年度与えた証明は、 Floer理論の枠組みで扱うことができる。さらに、この拡張した定理の系として、「滑らかな2次元結び目のSeifert超曲面の複雑さ」と「結び目群の複雑さ」を結びつけた。この結びつきを与える定理は、位相的結び目に対して成立しなこともわかっている。
・第2に、有向ホモロジーS^3の不変量r_s(Y)を導入し、 連結和に対する振る舞いを調べた。
この不変量はホモロジー同境不変量である. この性質を用いることで、あるクラスのホモロジーS^1×S^3の不変量が得られる。いくつかのホモロジーS^1×S^3での具体計算も行った。
