The following phase portraits are conjectured not to exist. If anyone finds an example of them, please report it to joancarles.artes@uab.cat.

We deploy the 7 phase portraits that were conjectured impossible in Structurally Unstable Quadratic Vector Fields of Codimension One plus the new five added in Structurally Unstable Quadratic Vector Fields of Codimension Two: Families Possessing One Finite Saddle-Node and a Separatrix Connection .

Of course, any higher codimension phase portrait which may bifurcate in any of them, is also wanted.

Moreover, any phase portrait having more limit cycles that those already mentioned in the previous Section, are also welcome.

DEAD OR ALIVE!!!
