Query: Equivariant Hirzebruch class for quadratic cones via degenerations   We compute the equivariant Hirzebruch class of the quadric cone in C^n
degenerating it to an intersection to hyperplanes. The difference of the
Hirzebruch classes (measured by the Milnor class) turns out to be the
Hirzebruch class of the complement of the quadratic cone of smaller dimension.
