Quartic differential systems with a non-degenerate monodromic critical point and multiple line at infinity
The quartic differential systems with a non-degenerate monodromic critical point and non-degenerate infinity Lacrosse - Sticks - Shafts are considerated.We show that in this family the maximal multiplicity of the line at infinity is seven.Modulo the affine transformation and time rescaling the classes of systems with the line of infinity of multipl
