Logarithmic resolution via weighted toroidal blow-ups
Abstract
Let be a fs logarithmic scheme that is generically logarithmically smooth, and that admits a strict closed embedding into a logarithmically smooth scheme over a field of characteristic zero. We construct a simple and fast procedure to functorial logarithmic resolution of , where the end result is in particular a stack-theoretic modification such that is logarithmically smooth over . In particular, if is a closed subscheme of a smooth -scheme , 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.)
