Thom series in negative relative codimension

László M. Fehér, Ákos K. Matszangosz

We develop a theory of Thom series for contact function singularities. Quadratic stabilization $σ_{q}$ of a contact singularity $η \in J^{k} (n, 1)$ gives contact singularities $σ_q^{i}η\…

Positivity in classical enumerative geometry: a case study in synchronized AI-assisted mathematics

Gergely Bérczi, László M. Fehér

We study the symmetric polynomial $\prod_{α \in A_{n, d}} (1 + α_{1} x_{1} + \dots + α_{n} x_{n})$ where $A_{n, d} := {α \in Z_{\geq 0}^{n} : ∣ α ∣ = d}$ , which is the total Chern class of…

Polynomiality of the Striling coefficients of $c (Pol^{d} (C^{n}))$ and Fano schemes

László M. Fehér, András P. Juhász

We prove that the $d$ -dependence of $c (Pol^{d} (C^{n}))$ , the Chern class of the $GL (n)$ -representation of degree $d$ homogeneous polynomials in $n$ complex v…

Obstructions for Morin and fold maps: Stiefel-Whitney classes and Euler characteristics of singularity loci

László M. Fehér, Ákos K. Matszangosz

For a singularity type $η$ , let the $η$ -avoiding number of an $n$ -dimensional manifold $M$ be the lowest $k$ for which there is a map $M \to R^{n + k}$ without $η$ type singul…

Plücker formulas using equivariant cohomology of coincident root strata

László M. Fehér, András P. Juhász

We give a new method to calculate the universal cohomology classes of coincident root loci. We show a polynomial behavior of them and apply this result to prove that generalized Pl…
