On k-rational and k-Du Bois local complete intersections

Algebraic Geometry 2024-03-19 v3

Abstract

We show that k-rational singularities of local complete intersections are k-Du Bois. For hypersurfaces, we characterize k-rationality in terms of the minimal exponent. We also establish some local vanishing results for k-rational and k-Du Bois singularities. Some of these results have been independently obtained in [FL2].
