Phase Transitions in Systems of Interacting Species
Margarita Ifti, Birger Bergersen
We discuss an autocatalytic reaction system: the cyclic competition model A1 + A2 --> 2 A2, A2 + A3 --> 2 A3, A3 + A4 --> 2 A4, A4 + A1 --> 2 A1), as well as its neutral counterpar…
Effects of neighbourhood size and connectivity on spatial Continuous Prisoner's Dilemma
Margarita Ifti, Timothy Killingback, Michael Doebeli
The Prisoner's Dilemma, a 2-person game in which the players can either cooperate or defect, is a common paradigm for studying the evolution of cooperation, when individuals exhibi…
Crossover Behaviour of 3-Species Systems with Mutations or Migrations
Margarita Ifti, Birger Bergersen
We study the ABC model in the cyclic competition and neutral drift versions, with mutations and migrations introduced into the model. When stochastic phenomena are taken into accou…
Survival and Extinction in Cyclic and Neutral Three--Species Systems
Margarita Ifti, Birger Bergersen
We study the ABC model (A + B --> 2B, B + C --> 2C, C + A --> 2A), and its counterpart: the three--component neutral drift model (A + B --> 2A or 2B, B + C --> 2B or 2C, C + A -->…
