Qualitative analysis of phase--portrait for a class of planar vector fields via the comparison method

Timoteo Carletti, Lilia Rosati, Gabriele Villari

The phase--portrait of the second order differential equation: $x ¨ + l = 0 \sum n f_{l} (x) x ˙^{l} = 0,$ is studied. Some results concerning existence, non--existence and uniquen…
