Abstract:  Differentiable mappings of smooth manifolds possess
singularities. The cohomology class Poincare dual to the locus of
particular singularity type is expressed as a universal polynomial
(known as the Thom polynomial) in the characteristic classes of
manifolds participating in the mapping. The very existence of such
polynomial provides also a way of its explicit computation. This leads
to an efficient solution of many enumerative problems of complex
projective enumerative geometry. We will discuss details of this
approach to enumerative geometry as well as some variations of the
Thom polynomial theory including enumeration of isolated hypersurface
singularities, singularities of wave fronts, and multisingularities of
various kinds.
