Positivity of Thom polynomials II: the Lagrange singularities
arXiv:0710.5251
Abstract
We show that Thom polynomials of Lagrangian singularities have nonnegative coefficients in the basis consisting of Q-functions. The main tool in the proof is nonnegativity of cone classes for globally generated bundles.
