On Gorenstein $Q_{p}$ -rational threefold and fourfold singularities

Jefferson Baudin, Zsolt Patakfalvi, Linus RÃ¶sler +1

We prove that for $n \leq 4$ and $p > 5$ , quasi--Gorenstein $F$ --pure and $Q_{p}$ --rational $n$ --fold singularities are canonical. This is analogous to the usual fact that r…

The weak Beauville--Bogomolov decomposition in characteristic $p \geq 0$

Zsolt Patakfalvi, Maciej Zdanowicz

We prove a variant of the Beauville--Bogomolov decomposition for weakly ordinary, or generally globally $F$ -split, varieties $X$ with $K_{X} \sim 0$ , in characteristic $p > 0$ . We also…
