Resumen de Limit cycles in the Holling-Tanner model

Robert E. Kooij Árbol académico, Joan Torregrosa Arús Árbol académico, Armengol Gasull i Embid Árbol académico

  • This paper deals with the following question: does the asymptotic stability of the positive equilibrium of the Holling-Tanner model imply it is also globally stable? We will show that the answer to this question is negative. The main tool we use is the computation of Poincaré-Lyapunov constants in case a weak focus occurs. In this way we are able to construct an example with two limit cycles.
