Compactifying the space of stable maps

Dan Abramovich, Angelo Vistoli

We define two equivalent notions of twisted stable map from a curve to a Deligne-Mumford stack with projective moduli space, and we prove that twisted stable maps of fixed degree f…

Torification and Factorization of Birational Maps

Dan Abramovich, Kalle Karu, Kenji Matsuki +1

Building on the work of the fourth author in math.AG/9904074, we prove the weak factorization conjecture for birational maps in characteristic zero: a birational map between comple…
