Radicalization phenomena: Phase transitions, extinction processes and control of violent activities
Abstract
In this work, we study a simple mathematical model to analyze the emergence and control of radicalization phenomena. The population consists of core and sensitive subpopulations, and their ways of life may be at least partially incompatible. In such a case, if a conflict exists, core agents act as inflexible individuals about the issue. On the other hand, the sensitive agents choose between two options: live peacefully with core population, or oppose it. This kind of modeling was recently considered by Galam and Javarone (2016) with constant pairwise couplings. Here, we consider the more general case with time-dependent transition rates, with the aim of study the impact of such time dependence on the critical behavior of the model. The analytical and numerical results show that the nonequilibrium active-absorbing phase transition can be suppressed in some cases, with the destruction of the absorbing phase where the radical agents disappear of the population in the stationary states.
