Positivity of Thom polynomials II: the Lagrange singularities

Malgorzata Mikosz, Piotr Pragacz, Andrzej Weber

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…

Thom polynomials of invariant cones, Schur functions, and positivity

Piotr Pragacz, Andrzej Weber

We generalize the notion of Thom polynomials from singularities of maps between two complex manifolds to invariant cones in representations, and collections of vector bundles. We p…

Thom polynomials and Schur functions: the singularities I_{2,2}(-)

Piotr Pragacz

We give the Thom polynomials for the singularities $I_{2, 2}$ associated with maps $(C^{∙}, 0) \to (C^{∙+ k}, 0)$ with parameter $k \geq 0$ . Our computations comb…
