K2-regularity and normality
Abstract
We take a fresh look at the relationship between K-regularity and regularity of schemes, proving two results in this direction. First, we show that K2-regular affine algebras over fields of characteristic zero are normal. Second, we improve on Vorst's K-regularity bound in the case of local complete intersections; this is related to recent work on higher du Bois singularities.
