    • Weierstrass integrability in Liénard differential systems 

      Giné, Jaume; Llibre, Jaume (Elsevier, 2011)
      In this work we study the Liénard differential systems that admit a Weierstrass first integral or a Weierstrass inverse integrating factor
    • Weierstrass integrability of differential equations 

      Giné, Jaume; Grau Montaña, Maite (Elsevier, 2010)
      The integrability problem consists in finding the class of functions a first integral of a given planar polynomial differential system must belong to. We recall the characterization of systems which admit an elementary or ...
    • Zero-Hopf polynomial centers of third-order differential equations 

      García, I. A. (Isaac A.); Valls, Claudia (Springer Science+Business Media New York, 2016-11-15)
      We study the 3-dimensional center problem at the zero-Hopf singularity in some families of polynomial vector fields arising from third-order polynomial differential equations. After proving some general properties we check ...
