Local vanishing for F-pure threefolds

Algebraic Geometry 2026-04-17 v1

Abstract

We establish Grauert--Riemenschneider vanishing for FF-pure threefolds over a perfect field kk of characteristic p>5p>5. We apply this to prove Steenbrink vanishing for three-dimensional sharply FF-pure pairs in characteristic p>5p>5. As a consequence, we obtain the logarithmic extension for one-forms in this setting.
