Abstract: Assume that X is a surface over an algebraically closed field k. 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).
