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…

Halving spaces and lower bounds in real enumerative geometry

László M. Fehér, Ákos K. Matszangosz

We develop the theory of halving spaces to obtain lower bounds in real enumerative geometry. Halving spaces are topological spaces with an action of a Lie group $Γ$ with additional…

Motivic Chern classes of cones

László M. Fehér

We study motivic Chern classes of cones. First we show examples of projective cones of smooth curves such that their various $K$ -classes (sheaf theoretic, push-forward and motivic)…

Additive Combinatorics Using Equivariant Cohomology

László M. Fehér, János Nagy

We introduce a geometric method to study additive combinatorial problems. Using equivariant cohomology we reprove the Dias da Silva-Hamidoune theorem. We improve a result of Sun on…
