Local vanishing for F-pure threefolds

arXiv:2604.14760

Abstract

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