Abstract

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