By replacing the features in which a high degree of consensus is achieved by new ones, we address here an essential ingredient of societies: the evolution of topics as a result of social dynamics and debate. Our results show that, once cultural clusters have been formed, the introduction of new topics into the social debate has little effect on them, but it does have a significant influence on the cultural overlap. Along with the Monte Carlo simulations, we derive and numerically solve an equation for the stationary cultural overlap based on a mean-field approach which reproduces the qualitative behavior of the model.2018http://zaguan.unizar.es/record/7914810.1016/j.physa.2018.06.023http://zaguan.unizar.es/record/79148oai:zaguan.unizar.es:79148info:eu-repo/grantAgreement/ES/MINECO/FIS2017-87519-PThis project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 662725-IBSENinfo:eu-repo/grantAgreement/EC/H2020/662725/EU/Bridging the gap: from Individual Behaviour to the Socio-tEchnical MaN/IBSENPhysica A: Statistical Mechanics and its Applications 509 (2018), 492-500by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
