## Thom polynomials of Morin singularities.(English)Zbl 1247.58021

Authors’ abstract: We prove a formula for Thom polynomials of $$A_d$$ singularities in any codimension. We use a combination of the test-curve model of Porteous, and the localization methods in equivariant cohomology. Our formulas are independent of the codimension, and are computationally effective up to $$d=6$$.
