Deformation Formulas for Parameterized Hypersurfaces
Deformation Formulas for Parameterized Hypersurfaces
We investigate one-parameter deformations of functions on affine space which define parameterizable hypersurfaces. With the assumption of isolated polar activity at the origin, we are able to completely express the Lê numbers of the special fiber in terms of the Lê numbers of the generic fiber and the characteristic polar …
