Loops on schemes and the algebraic fundamental group
Kay Rülling, Stefan Schröer
In this note we give a re-interpretation of the algebraic fundamental group for proper schemes that is rather close to the original definition of the fundamental group for topologi…
The resolution property holds away from codimension three
Siddharth Mathur, Stefan Schröer
The purpose of this paper is to verify a conjecture of Gross under mild hypothesis: all reduced, separated, and excellent schemes have the resolution property away from a closed su…
The structure of Frobenius kernels for automorphism group schemes
Stefan Schröer, Nikolaos Tziolas
We establish structure results for Frobenius kernels of automorphism group schemes for surfaces of general type in positive characteristics. It turns out that there are surprisingl…
Discriminant groups of wild cyclic quotient singularities
Dino Lorenzini, Stefan Schröer
Let p be prime. We describe explicitly the resolution of singularities of several families of wild Z/pZ-quotient singularities in dimension two, including families that generalize…
Para-abelian varieties and Albanese maps
Bruno Laurent, Stefan Schröer
We construct for every proper algebraic space over a ground field an Albanese map to a para-abelian variety, which is unique up to unique isomorphism. This holds in the absence of…
