2024-12-05T21:57:36Z urn:hdl:10459.1/60389 On the planar integrable differential systems Giné, Jaume Llibre, Jaume Under very general assumptions we prove that the planar differential systems having a first integral are essentially the linear differential systems u˙ = u, ˙v = v. Additionally such systems always have a Lie symmetry. We improve these results for polynomial differential systems defined in R2 or C2.
