Abstract:

Along the last ten years, D. Schlomiuk, N. Vulpe, J. Llibre and J.C. Artés have been working in the geometrical classification of singularities (finite and infinite) of planar quadratic differential systems. Seven partial papers have been produced and finally a book containing all them plus lattest most generic cases has been completed. We present these results altogether with a Mathematica tool that allows an easy way to study families of quadratics systems with some parameters and determine easily the bifurcation diagram related to the singularities.
