Principalization of ideals on toroidal orbifolds

Algebraic Geometry 2017-09-12 v1

Abstract

Given an ideal I\mathcal I on a variety XX with toroidal singularities, we produce a modification XXX' \to X, functorial for toroidal morphisms, making the ideal monomial on a toroidal stack XX'. We do this by adapting the methods of [W{\l}o05], discarding steps which become redundant. We deduce functorial resolution of singularities for varieties with logarithmic structures. This is the first step in our program to apply logarithmic desingularization to a morphism ZBZ \to B, aiming to prove functorial semistable reduction theorems.
