Saturation of Jacobian ideals: Some applications to nearly free curves, line arrangements and rational cuspidal plane curves

Participant : Alexandru Dimca.

In [6] we describe the minimal resolution of the ideal $I_{f}$ , the saturation of the Jacobian ideal of a nearly free plane curve $(C : f) = 0$ . In particular, it follows that this ideal $I_{f}$ can be generated by at most 4 polynomials. Some applications to rational cuspidal plane curves are given, and a natural related question is raised.

This is a joint work with Gabriel Sticlaru (Ovidius University of Constanta).
