In this talk I will present the results obtained up to now for a systematic classification of phase portraits of planar quadratic differential equations, and the available tools needed to complete this work. Up to now, this work is achievable only if we limit ourselves to phase portraits modulo limit cycles, that is, without considering how many limit cycles a portrait has. Even with this strong restriction, the number of different phase portraits seems to be over 1000 and even close to 2000. |
