Title: | Noncommutative resolutions and rational singularities | Authors: | Stafford, J. T. VAN DEN BERGH, Michel |
Issue Date: | 2008 | Publisher: | MICHIGAN MATHEMATICAL JOURNAL | Source: | MICHIGAN MATHEMATICAL JOURNAL, 57. p. 659-674 | Abstract: | Let k be an algebraically closed field of characteristic zero. We show that the centre of a homologically homogeneous, finitely generated k-algebra has rational singularities. In particular if a finitely generated normal commutative k-algebra has a noncommutative crepant resolution, as introduced by the second author, then it has rational singularities. | Notes: | [Van den Bergh, M.] Univ Hasselt, Dept WNI, B-3590 Diepenbeek, Belgium.
