• openAccess   Detection of special curves via the double resultant 

      Ferragut, Antoni; García-Saldaña, Johanna Denise; Gasull, Armengol Springer Verlag (2017)
      We introduce several applications of the use of the double resultant through some examples of computation of different nature: special level sets of rational first integrals for rational discrete dynamical systems; remarkable ...
    • 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 ...
