Research Abstract |
The secondarycohomology 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-thStiefel-Whitney class of the source 4-manifold would be the secondary obstructionclass for eliminating cusp singularities of the smooth map.
