Motivic zeta function of the Hilbert schemes of points on a surface

Abstract

Let $K$ be a discretely-valued field. Let $X\to SpecK$ be a surface with trivial canonical bundle. In this paper we construct a weak Néron model of the schemes $Hil{b}^n(X)$ over the ring of integers $R\subseteq K$. We exploit this construction in order to compute the Motivic Zeta Function of $Hil{b}^n(X)$ in terms of $Z_X$. We determine the poles of $Z_{Hil{b}^n(X)}$ and study its monodromy property, showing that if the monodromy conjecture holds for $X$ then it holds for $Hil{b}^n(X)$ too. Sit $K$ corpus cum absoluto ualore discreto. Sit $X\to SpecK$ leuigata superficies cum canonico fasce congruenti ${\mathcal{O}}_X$. In hoc scripto defecta Neroniensia paradigmata $Hil{b}^n(X)$ schematum super annulo integrorum in $K$ corpo, $R\subset K$, constituimus. Ex hoc, Functionem Zetam Motiuicam $Z_{Hil{b}^n(X)}$, dato $Z_X$, computamus. Suos polos statuimus et suam monodromicam proprietatem studemus, coniectura monodromica, quae super $X$ ualet, ualere super $Hil{b}^n(X)$ quoque demostrando.
