We present a metapopulation dynamic model for the diffusively-coupled rock-paper-scissors (RPS) game with mutation in scale-free hierarchical networks. We investigate how the RPS game changes by mutation in scale-free networks. Only the mutation from

Abstract Predator-prey systems have been studied intensively for over a hundred years. These studies have demonstrated that the dynamics of Lotka-Volterra (LV) systems are not stable, that is, exhibiting either cyclic oscillation or divergent extinct

Abstract Understanding mechanisms of biodiversity has been a central question in ecology. The coexistence of three species in rock-paper-scissors (RPS) systems are discussed by many authors; however, the relation between coexistence and network struc

We study the traffic states and fundamental diagram of vehicular traffic controlled by a series of traffic lights using a deterministic cellular automaton (CA) model. The CA model is not described by a set of rules but is given by a difference equati

We study the effect of the network structure on the dynamic stability in the diffusively coupled Lotka–Volterra system. Here we present a metapopulation model for the Lotka–Volterra system on various graphs. The total population is assumed to con

We study how the Allee effect with diffusion changes depending on the graph topology. We present the metapopulation dynamic model on heterogeneous and homogeneous graphs for the Allee effect of mobile individuals. We consider the small graphs with th

Much literature exists on temporal networks for epidemic spreading. We present a metapopulation dynamic model on a temporal network; a subpopulation (patch) is represented by a node on a graph, and a link represents a migration path between patches.
