Verhulst-Lotka-Volterra (VLV) model of ideological struggles
Let the population of e.g. a country where some opinion struggle occurs be
varying in time, according to Verhulst equation. Consider next some competition
between opinions such as the dynamics be described by Lotka and Volterra
equations. Two kinds of influences can be used, in such a model, for describing
the dynamics of an agent opinion conversion: this can occur (i) either by means
of mass communication tools, under some external field influence, or (ii) by
means of direct interactions between agents. It results, among other features,
that change(s) in environmental conditions can prevent the extinction of
populations of followers of some ideology due to different kinds of
resurrection effects. The tension arising in the country population is proposed
to be measured by an appropriately defined scale index.Comment: based on N.K. Ivanov invited paper at Dyses 2010
