The singularities of the principal component of the Hilbert scheme of points

Kyungyong Lee

We show that the principal component of the Hilbert scheme of 9 points in C^8 is not Cohen-Macaulay.

Duality and monodromy reducibility of -hypergeometric systems

Uli Walther

We study -hypergeometric systems in the sense of Gelfand, Kapranov and Zelevinsky under two aspects: the structure of their holonomically dual system, and reducibility…

Analytic cell decomposition and analytic motivic integration

R. Cluckers, L. Lipshitz, Z. Robinson

The main results of this paper are a Cell Decomposition Theorem for Henselian valued fields with analytic structure in an analytic Denef-Pas language, and its application to analyt…

Homological Methods for Hypergeometric Families

Laura Felicia Matusevich, Ezra Miller, Uli Walther

We analyze the behavior of the holonomic rank in families of holonomic systems over complex algebraic varieties by providing homological criteria for rank-jumps in this general set…

Genus 2 mapping class groups are not Kahler

Razvan Veliche

The goal of these notes is to prove that the mapping class groups of a closed orientable surface of genus two, with punctures, are not Kähler

Simple Hironaka resolution in characteristic zero

Jaroslaw Wlodarczyk

Building upon work of Villamayor and Bierstone-Milman we give a proof of the canonical Hironaka principalization and desingularization. The idea of "homogenized ideals" introduced…
