This paper proposes a generalization of the Hawk-Dove Game for an arbitrary number of agents: the N-person Hawk-Dove Game. In this model, doves exemplify the cooperative behavior without intraspecies conflict, while hawks represent the aggressive behavior. In the absence of hawks, doves share the resource equally and avoid conflict, but having hawks around lead to doves escaping without fighting. Conversely, hawks fight for the resource at the cost of getting injured. Nevertheless, if doves are present in sufficient number to expel the hawks, they can aggregate to protect the resource, and thus avoid being plundered by hawks. We derive and numerically solve an exact equation for the evolution of the system in both finite and infinite well-mixed populations, finding the conditions for stable coexistence between both species. Furthermore, by varying the different parameters, we found a scenario of bifurcations that leads the system from dominating hawks and coexistence to bi-stability, multiple interior equilibria and dominating doves. info:eu-repo/grantAgreement/ES/MINECO/FIS2014-55867-P This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 662725-IBSEN info:eu-repo/grantAgreement/EC/H2020/662725/EU/Bridging the gap: from Individual Behaviour to the Socio-tEchnical MaN/IBSEN info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.122 2017 MULTIDISCIPLINARY SCIENCES 12 / 64 = 0.188 2017 Q1 T1 1.533 2017 Multidisciplinary 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-9769-8796 Gracia-Lázaro, Carlos Li, Zhiwu Wang, Long (orcid)0000-0002-0895-1893 Moreno, Yamir Universidad de Zaragoza 2004 405 Universidad de Zaragoza Dpto.
