Factoring 3-fold flips and divisorial contractions to curves

Algebraic Geometry 2009-10-23 v1

Abstract

We show that 3-fold terminal flips and divisorial contractions to a curve may be factored by a sequence of weighted blow-ups, flops, blow-downs to a locally complete intersection curve in a smooth 3-fold or divisorial contractions to a point.
