Stability of pencils of plane curves
Aline Zanardini (Leiden University)
Abstract: In this talk I will discuss some recent results on the problem of classifying pencils of plane curves up to projective equivalence. We will see how the stability of a pencil is related to the stability of its generators, to the log canonical threshold, and to the multiplicities of a base point. In particular, I will present complete stability criteria for certain pencils of plane sextics called Halphen pencils of index two.
