The Thom polynomial of a singularity is a universal characteristic class which expresses the fundamental cohomology class of the singularity submanifold of a map, in terms of the Chern classes of its source and target manifolds. For more details click “Thom polynomials” in the menu above.

In this website we collect the known Thom polynomials.
