Resumen de Gromov-Witten theory of Deligne-Mumford stacks

Dan Abramovich, Tom Graber, Angelo Vistoli

• Given a smooth complex Deligne-Mumford stack ${\cal X}$ with a projective coarse moduli space, we introduce Gromov-Witten invariants of ${\cal X}$ and prove some of their basic properties, including the WDVV equation.
