Syzygies and logarithmic vector fields along plane curves
  We investigate the relations between the syzygies of the Jacobian ideal of the defining equation for a plane curve $C$ and the stability of the sheaf of logarithmic vector fields along $C$, the freeness of the divisor $C$ and the Torelli properties of $C$ (in the sense of Dolgachev-Kapranov).   We show in particular that curves with a small number of nodes and cusps are Torelli in this sense.
