Invariant curves and integrability of planar cr differential systems

Antoni Ferragut, Jaume Llibre

Research output: Contribution to journalArticleResearchpeer-review


Copyright © 2018 Rocky Mountain Mathematics Consortium. We improve the known expressions of the Cr differential systems in the plane having a given Cr+1 invariant curve, or a given Cr+1 first integral. Their application to polynomial differential systems having either an invariant algebraic curve, or a first integral, also improves the known results on such systems.
