          <datacite:description descriptionType="Abstract">研究成果の概要(和文): 微分可能多様体の間の滑らかな生成的写像に現れる特異点のThom多項式以外の障害として、二次コホモロジー類が定義される。4次元多様体の間の生成的写像に対して、定義域4次元多様体の4次のStiefe1-Whitney類が尖点を消去するための二次障害類であることを証明した。                          研究成果の概要(英文): The secondary cohomology class of singularity for a generic smooth map between differentiable manifolds can be defined as an obstruction class other than the Thom polynomials of singularities. For a generic smooth map between 4-manifolds we have proved that the 4-th Stiefel-Whitney class of the source 4-manifold would be the secondary obstruction class for eliminating cusp singularities of the smooth map.</datacite:description>
