Thresholds of singularities in characteristic zero
Sandra Rodríguez-Villalobos, Karl Schwede
We study properties of characteristic zero variants of Frobenius thresholds inspired by the work of Epstein-McDonald-R.G. and the second author. Suppose is a…
-injectivity does not deform
Karl Schwede, Austyn Simpson
We show that there exists an -finite four-dimensional local domain of characteristic two which is not -injective but which admits a nonzerodivisor $f\in \m…
Factoring maps to big Cohen-Macaulay algebras through blowups
Karl Schwede
We show that for a reduced universally catenary equidimensional Noetherian local ring , any sufficiently functorial big Cohen-Macaulay algebra assignment , and an…
-finite schemes have a dualizing complex
Bhargav Bhatt, Manuel Blickle, Karl Schwede +1
In this paper we show that any Noetherian -finite scheme has a dualizing complex with the property that for all finite type maps between …
The Briançon-Skoda theorem for pseudo-rational and Du Bois singularities and uniformity in excellent rings
Linquan Ma, Peter M. McDonald, Rebecca R. G. +1
Suppose is an -generated ideal in any ring . We prove a general Briançon-Skoda-type containment relating the integral closure w…
Bounds on the plus-pure thresholds of some hypersurfaces in (ramified) regular rings
Marta Benozzo, Vignesh Jagathese, Vaibhav Pandey +3
We study the plus-pure threshold (ppt) of hypersurfaces in mixed characteristic. We show that the ppt limits to the -pure threshold (fpt) as we ramify the base DVR. Additionally…
