    • openAccess   A class of polynomial planar vector fields with polynomial first integral 

      Ferragut, Antoni; Galindo, Carlos; Monserrat, Francisco Elsevier (2015-10)
      We give an algorithm for deciding whether a planar polynomial differential system has a first integral which factorizes as a product of defining polynomials of curves with only one place at infinity. In the affirmative ...

    • openAccess   Quantitative analysis of competition models 

      Chiralt, Cristina; Ferragut, Antoni; Gasull, Armengol; Vindel, Pura Elsevier (2017)
      We study a 2-species Lotka–Volterra type differential system, modeling competition between two species and having a coexistence equilibrium in the first quadrant. In case that this equilibrium is of saddle type, its ...
