| Outline of Final Research Achievements |
The Alexander polynomial is the most classical polynomial invariant for knots, which is always important in Knot Theory and Low dimensional Topology.From the fact that the Alexander polynomial is deeply related with the Reidemeister torsion, which is an invariant for 3-dimensional manifolds, via surgery formula, I have studied the value of the Reidemeister torsion of lens spaces and Seifert manifolds by using the facts from cyclotomic field theory.

| Academic Significance and Societal Importance of the Research Achievements |
アレクサンダー多項式は学術的に様々な方面に応用できる。私が研究で行った主な応用は、手術理論、絡み目の対称性問題、結び目理論と数論の関連性の理論である。特に数論との関連性からわかるように、今後も他分野との関わりを広げられる可能性を秘めていると確信する。
