Abstract

During the last decades the way of forming an opinion has changed in two main directions: the structure of the network (epistemic bubble), the epistemic process driving our mind (echo chamber). In this project we show how a mathematical model could describe the evolution of the opinion towards a radicalized and polarized distribution. Contrary to the usual local interaction in this case we consider global interaction, according to the globalisation of the news and the networks. Interesting applications to social network's structures arise.
