A discrete in time model of ideological competition is formulated taking into account population migration. The model … competition can happen in one or several regions in space. In the latter case, migration of non-believers and adepts is allowed …

Computer simulations of complex food-webs are important tools for deepening our understanding of these systems. Yet most computer models assume, rather than generate, key system-level patterns, or use mathematical modeling approaches that make it difficult to fully account for nonlinear...

We show that any quasi-polynomial invariant of a quasi-polynomial dynamical system can be transformed into a quasi-polynomial invariant of a homogeneous quadratic Lotka–Volterra dynamical system. We show how this quasi-polynomial invariant can be decomposed in a simple manner. This...

In this paper, we deal with a discrete n-species non-autonomous Lotka–Volterra competitive systems with infinite delays and feedback control, obtain sufficient conditions for the permanence of the systems.

The generalized Lotka–Voltera (GLV) formalism has been introduced in order to explain the power law distributions in the individual wealth (wi(t)) (Pareto law) and financial markets returns (fluctuations) (r) as a result of the auto-catalytic (multiplicative random) character of the individual...

This paper analyzes a model for the competition dynamics of web sites in the Internet, based on the Lotka …–Volterra competition equations. This model shows the well known appearance of a winner-take-all characteristic and is based in the … competition between sites. …

In this report we study the dynamics characteristics of conversations among several participants, analyzing trunked mobile telephony databases. We find that the duration of the dialogue sessions deviates systematically from the predictions of Poisson statistics, following probability...

We introduce neighborhood models that account for local spatial effects in Galam's model [1] of minority opinion spreading. This model describes the spread of a minority opinion, incorporating absic mechanisms of social inertia, resulting in democratic rejection of social reforms initially...
