The main aim of my talk is to present the notion of Poincare polynomials of plane curves with quasi-homogeneous singularities. At the first step we show how to define such an object for conic-line arrangements with ordinary quasi-homogeneous singularities, and then we focus on arrangements of conics with some ADE singularities. Then I report on the addition technique that can be used to construct new examples of free plane curves.
The talk is based on the recent preprints by the author.
