Research Abstract

P^5の中の3次元セグレ多様体の十分一般な線形射影によるP^4への像の定義方程式を具体的に求め, この例を通して, これまで得られていた, P^4の中の通常特異点を持つ超曲面の正規化のチャーン数を与える公式(S. Tsuboi : The Chern numbers of the normalization of an algebraic threefold with ordinary singularities, Seminaires et Congres 10, Soc. Math. France, 351-372, 2005)に誤りがあることに気が付き, この公式を修復した.
