Let (X) over tilde be obtained from X by blowing up a smooth point and let L be the exceptional curve. Let coh(X) be the category of coherent sheaves on X. In this note we show how to recover coh(X) from coh((X) over tilde), if we know the object O L (L). | Notes: | Limburgs Univ Ctr, Dept WNI, B-3590 Diepenbeek, Belgium.Van den Bergh, M, MIT, Dept Math, 77 Massachusetts Ave, Cambridge, MA 02139 USA. | Keywords: | blowing down | Document URI: | http://hdl.handle.net/1942/2883 | ISI #: | 000083449800008 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2000 |
