Logarithmic resolution via weighted toroidal blow-ups

Abstract

Let XX be a fs logarithmic scheme that is generically logarithmically smooth, and that admits a strict closed embedding into a logarithmically smooth scheme YY over a field \kk\kk of characteristic zero. We construct a simple and fast procedure to functorial logarithmic resolution of XX, where the end result is in particular a stack-theoretic modification XXX' \rightarrow X such that XX' is logarithmically smooth over kk. In particular, if XX is a closed subscheme of a smooth kk-scheme YY, the procedure not only shares the same desirable features as the 'dream resolution algorithm' of Abramovich-Temkin-Wlodarczyk (arXiv:1906.07106), but also accounts for a key feature of Hironaka's Main Theorem I, which was not addressed in arXiv:1906.07106. As a consequence, we recover a different and simpler approach to Hironaka's resolution of singularities in characteristic zero.

Comments

Updated to the published version, with a slight edit to the abstract. Note: Theorem 1.1 in the published version has the word "generically" appearing at the wrong place. Fixed in this version. (I thank Simon Felten for pointing out that the previous version was not updated to the published version.)
